Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation
	The accounting policies followed by Western Digital Corporation (the “Company”) are set forth in Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended June 28, 2013. In the opinion of management, all adjustments necessary to fairly state the unaudited condensed consolidated financial statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 28, 2013. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.
	On July 10, 2013, the Company acquired VeloBit, Inc. ("VeloBit") and on September 12, 2013, the Company completed its acquisition of sTec, Inc. (“sTec”). These acquisitions are further described in Note 11 below. In connection with the acquisitions, VeloBit and sTec became indirect wholly-owned subsidiaries of the Company. VeloBit and sTec’s results of operations since the dates of acquisition are included in the condensed consolidated financial statements.
	Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.

	Warranty
	The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs, and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assist the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected. Changes in the warranty accrual were as follows (in millions):

	The long-term portion of the warranty accrual classified in other liabilities was $72 million at September 27, 2013 and $73 million at June 28, 2013.
	Other Comprehensive Income (Loss)
	Other comprehensive income (loss) refers to revenue, expenses, gains and losses that are recorded as an element of shareholders’ equity but are excluded from net income. The Company’s other comprehensive income (loss) is comprised of unrealized gains and losses on foreign exchange contracts and actuarial gains and losses related to pensions. The income tax impact on components of other comprehensive income is immaterial for all periods presented.

Earnings Per Share [Abstract]
Income per Common Share	3. Income per Common Share
	The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards (“RSUs”).
	The following table illustrates the computation of basic and diluted income per common share (in millions, except per share data):

Debt Disclosure [Abstract]
Debt	4. Debt
	On March 8, 2012 (the “HGST Closing Date”), the Company, in its capacity as the parent entity and guarantor, Western Digital Technologies, Inc. (“WDT”), a wholly owned subsidiary of the Company, and Western Digital Ireland, Ltd. (“WDI”), an indirect wholly owned subsidiary of the Company, entered into a five-year credit agreement (the “Credit Facility”) with Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer, and certain other participating lenders (collectively, the “Lenders”). The Credit Facility provided for $2.8 billion of unsecured loan facilities consisting of a $2.3 billion term loan facility and a $500 million revolving credit facility. The only borrower under the term loan facility is WDI and the revolving credit facility is available to both WDI and WDT (WDI and WDT are referred to as “the Borrowers”). The Borrowers may elect to expand the Credit Facility by up to an additional $500 million if existing or new lenders provide additional term or revolving commitments. The obligations of the Borrowers under the Credit Facility are guaranteed by the Company and the Company’s material domestic subsidiaries, and the obligations of WDI under the Credit Facility are also guaranteed by WDT. During the three months ended September 27, 2013, WDT borrowed $500 million under the revolving credit facility.
	The term loans and the revolving credit loans may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions. As of September 27, 2013, the term loan facility and revolving credit facility had a variable interest rate of 2.18% and a total remaining outstanding balance of $2.4 billion. The Company is required to make principal payments on the term loan facility totaling $230 million a year for fiscal 2014 through fiscal 2016, and the remaining $1.3 billion balance (subject to adjustment to reflect prepayments or an increase to its term loan facility) is due and payable in full on March 8, 2017. The outstanding amount of the revolving credit facility is also required to be repaid by March 8, 2017. The Company intends to repay the revolving credit facility within one year; therefore, the outstanding balance of $500 million under the revolving credit facility is classified as a current liability on the condensed consolidated balance sheet.
	The Credit Facility requires the Company to comply with a leverage ratio and an interest coverage ratio calculated on a consolidated basis for the Company and its subsidiaries. In addition, the Credit Facility contains customary covenants, including covenants that limit or restrict, subject to certain exceptions, the Company’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge, consolidate or dispose of substantially all of its assets, and enter into certain speculative hedging arrangements and make any material change in the nature of its business. Upon the occurrence of an event of default under the Credit Facility, the administrative agent at the request, or with the consent, of the Required Lenders (as defined in the Credit Facility) may cease making loans, terminate the Credit Facility and declare all amounts outstanding to be immediately due and payable, require the cash collateralization of letters of credit and/or exercise all other rights and remedies available to it, the Lenders and the letter of credit issuer. The Credit Facility specifies a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults, material judgment defaults and a change of control default. As of September 27, 2013, the Company was in compliance with all covenants.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings	5. Legal Proceedings
	When the Company becomes aware of a claim or potential claim, the Company assesses the likelihood of any loss or exposure. The Company discloses information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, the Company records an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible or where a loss in excess of the amount accrued is reasonably possible, the Company discloses an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to the Company’s financial position, results of operations or cash flows. Unless otherwise stated below, for each of the matters described below, the Company has either recorded an accrual for losses that are probable and reasonably estimable or has determined that, while a loss is reasonably possible (including potential losses in excess of the amounts accrued by the Company), a reasonable estimate of the amount of loss or range of possible losses with respect to the claim or in excess of amounts already accrued by the Company cannot be made. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.
	Solely for purposes of this footnote, “WD” refers to Western Digital Corporation or one or more of its subsidiaries excluding HGST prior to the HGST Closing Date. HGST refers to Hitachi Global Storage Technologies Holdings Pte. Ltd. or one or more of its subsidiaries as of the HGST Closing Date, and “the Company” refers to Western Digital Corporation and all of its subsidiaries on a consolidated basis including HGST.
	Intellectual Property Litigation
	On June 20, 2008, plaintiff Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against WD, HGST, and one other company alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. The complaint sought unspecified monetary damages and injunctive relief. On October 10, 2008, Convolve amended its complaint to allege infringement of only the ‘473 patent. The ‘473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. A trial in the matter began on July 18, 2011 and concluded on July 26, 2011 with a verdict against WD and HGST in an amount that is not material to the Company’s financial position, results of operations or cash flows. WD and HGST have filed post-trial motions challenging the verdict and will evaluate their options for appeal after the Court rules on the post-trial motions.
	On December 7, 2009, plaintiff Nazomi Communications (“Nazomi”) filed a complaint in the Eastern District of Texas against WD and seven other companies alleging infringement of U.S. Patent Nos. 7,080,362 and 7,225,436. Nazomi dismissed the Eastern District of Texas suit after filing a similar complaint in the Central District of California on February 8, 2010. The case was subsequently transferred to the Northern District of California on October 14, 2010. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to processor cores capable of Java hardware acceleration. In August 2012, the Court dismissed WD on summary judgment for non-infringement. Nazomi filed a notice of appeal on January 16, 2013. The Federal Circuit hearing for the appeal is scheduled for November 4, 2013. WD intends to continue to defend itself vigorously in this matter.
	On August 1, 2011, plaintiff Guzik Technical Enterprises (“Guzik”) filed a complaint in the Northern District of California against WD and various of its subsidiaries alleging infringement of U.S. Patent Nos. 6,023,145 and 6,785,085, breach of contract and misappropriation of trade secrets. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The patents asserted by Guzik allegedly relate to devices used to test hard disk drive heads and media. WD has filed counterclaims against Guzik for patent infringement of U.S. Patent Nos. 5,844,420; 5,640,089; 6,891,696; and 7,480,116. The patents asserted by WD relate to devices and methods used in the testing of hard disk drive heads and media. WD intends to defend itself vigorously in this matter.
	On July 9, 2012, Siemens Aktiengesellschaft (“Siemens”) filed a complaint in German court alleging patent infringement of European patent no. EP 674769, which claims an artificial antiferromagnetic (AAF) (aka, synthetic antiferromagnetic) structure for giant magneto-resistive (GMR) sensors. On March 14-15, 2013, the Company filed a response of noninfringement and also filed a separate nullity action. Siemens separately served WD on July 15, 2013. WD responded on September 6, 2013. Siemens' response is due on December 31, 2013. The Company’s rejoinder will then be due on February 28, 2014. The oral hearing will be on March 11, 2014. The Company intends to defend itself vigorously in this matter.
	On April 29, 2013, plaintiffs Charles C. Freeney III et al. filed a complaint in the Eastern District of Texas against WD alleging infringement of U.S. Patent No. 7,110,744. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The patent allegedly relates to WD’s AC router products. WD intends to defend itself vigorously in this matter.
	On September 5, 2013, plaintiff Lake Cherokee Hard Drive Technologies, LLC (“Lake Cherokee”) filed a complaint in the Eastern District of Texas against: Marvell Asia PTE, Ltd., Samsung Semiconductor, Inc., Seagate Tech. LLC, Seagate Tech. Int’l., Toshiba Corp., Toshiba Am. Elec. Components, Toshiba Am. Inf. Sys., Inc., Toshiba Am. Inf. Equip. (Philippines), Inc., and Western Digital Technologies, Inc. alleging infringement of US Patent Nos. 5,844,738 and 5,978,162. Lake Cherokee alleges that WD’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’738 and ’162 patents. The complaint seeks unspecified monetary damages, fees and costs. The Company intends to defend itself vigorously in this matter.
	On September 5, 2013, plaintiff Lake Cherokee filed a complaint in the Eastern District of Texas against: Marvell Semiconductor, Inc., Marvell Asia PTE, Ltd., Dell Inc., and Western Digital Technologies, Inc. alleging infringement of US Patent No. 5,583,706. Lake Cherokee alleges that WD’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’706 patent. The complaint seeks an injunction, unspecified monetary damages, fees and costs. The Company intends to defend itself vigorously in this matter.
	On September 9, 2013, plaintiff Garnet Digital, LLC filed a complaint in the Eastern District of Texas against Western Digital Technologies, Inc., alleging infringement of US Patent No. 5,379,421. Garnet Digital alleges that the Company’s WD TV Live product infringes the ’421 patent. The complaint seeks unspecified monetary damages, fees and costs. The Company intends to defend itself vigorously in this matter.
	Seagate Matter
	On October 4, 2006, plaintiff Seagate Technology LLC (“Seagate”) filed an action in the District Court of Hennepin County, Minnesota, naming as defendants WD and one of its now former employees previously employed by Seagate. The complaint in the action alleged claims based on supposed misappropriation of trade secrets and sought injunctive relief and unspecified monetary damages, fees and costs. On June 19, 2007, WD’s former employee filed a demand for arbitration with the American Arbitration Association. A motion to stay the litigation as against all defendants and to compel arbitration of all Seagate’s claims was granted on September 19, 2007. On September 23, 2010, Seagate filed a motion to amend its claims and add allegations based on the supposed misappropriation of additional confidential information, and the arbitrator granted Seagate’s motion. The arbitration hearing commenced on May 23, 2011 and concluded on July 11, 2011.
	On November 18, 2011, the sole arbitrator ruled in favor of WD in connection with five of the eight alleged trade secrets at issue, based on evidence that such trade secrets were known publicly at the time the former employee joined WD. Based on a determination that the employee had fabricated evidence, the arbitrator then concluded that WD had to know of the fabrications. As a sanction, the arbitrator precluded any evidence or defense by WD disputing the validity, misappropriation, or use of the three remaining alleged trade secrets by WD, and entered judgment in favor of Seagate with respect to such trade secrets. Using an unjust enrichment theory of damages, the arbitrator issued an interim award against WD in the amount of $525 million plus pre-award interest at the Minnesota statutory rate of 10% per year. In his decision with respect to these three trade secrets, the arbitrator did not question the relevance, veracity or credibility of any of WD’s ten expert and fact witnesses (other than WD’s former employee), nor the authenticity of any other evidence WD presented. On January 23, 2012, the arbitrator issued a final award adding pre-award interest in the amount of $105.4 million for a total final award of $630.4 million. On January 23, 2012, WD filed a petition in the District Court of Hennepin County, Minnesota to have the final arbitration award vacated. A hearing on the petition to vacate was held on March 1, 2012.
	On October 12, 2012, the District Court of Hennepin County, Minnesota vacated, in full, the $630.4 million final arbitration award. Specifically, the Court confirmed the arbitration award with respect to each of the five trade secret claims that WD and the former employee had won at the arbitration and vacated the arbitration award with respect to the three trade secret claims that WD and the former employee had lost at the arbitration. The Court ordered that a rehearing be held concerning those three alleged trade secret claims before a new arbitrator.
	On October 30, 2012, Seagate initiated an appeal of the Court’s decision with the Minnesota Court of Appeals. On July 22, 2013, the Minnesota Court of Appeals reversed the District Court’s decision and remanded for entry of an order and judgment confirming the arbitration award. The Company strongly disagrees with the decision of the Court of Appeals and believes that the District Court’s decision was correct. On August 20, 2013, the Company filed a petition for review with the Minnesota Supreme Court and, on October 15, 2013, the Company was informed that the Minnesota Supreme Court granted the Company’s petition. The order of the Minnesota Supreme Court provides that the parties will file briefs with the Minnesota Supreme Court, and the Minnesota Supreme Court will subsequently set the matter for argument. The Company will continue to vigorously defend itself in this matter. In light of uncertainties with respect to this matter, the Company recorded an accrual of $681 million for this matter in its financial statements in the fourth quarter of fiscal 2013 and recorded additional interest totaling $13 million in the three months ended September 27, 2013, which is included within charges related to arbitration award in the condensed consolidated statement of income. This amount is in addition to the $25 million previously accrued in the fourth quarter of fiscal 2011. The total amount accrued of $719 million represents the amount of the final arbitration award, plus interest accrued on the initial arbitration award at the statutory rate of 10% from January 24, 2012 through September 27, 2013.
	Other Matters
	In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes
	The Company’s income tax provision for the three months ended September 27, 2013 was $37 million as compared to $59 million in the prior-year period. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2014 through 2025 and the current year generation of income tax credits.
	In the three months ended September 27, 2013, the Company recorded a net increase of $7 million in its liability for unrecognized tax benefits. As of September 27, 2013, the Company had a recorded liability for unrecognized tax benefits of approximately $247 million. Interest and penalties recognized on such amounts were not material to the condensed consolidated financial statements during the three months ended September 27, 2013.
	The Internal Revenue Service (“IRS”) completed its field examination of the Company’s federal income tax returns for fiscal years 2006 and 2007 and issued Revenue Agent Reports (“RARs”) that proposed adjustments to income before income taxes of approximately $970 million primarily related to transfer pricing and intercompany payable balances. The Company disagreed with the proposed adjustments and filed a protest with the IRS Appeals Office. In June 2013, the Company reached an agreement with the IRS to resolve the transfer pricing issue. This agreement resulted in a decrease in the amount of net operating loss and tax credits realized, but did not have an impact on the Company’s consolidated statements of income. The proposed adjustment relating to intercompany payable balances for fiscal years 2006 and 2007 will be addressed in conjunction with the IRS’s examination of the Company’s fiscal years 2008 and 2009, which commenced in January 2012. In addition, in January 2012, the IRS commenced an examination of the 2007 fiscal period ended September 5, 2007 of Komag, Incorporated, which was acquired by the Company on September 5, 2007. In February 2013, the IRS commenced an examination of calendar years 2010 and 2011 of HGST, which was acquired by the Company on March 8, 2012.
	The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of September 27, 2013, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.

	Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:
	Level 1. Quoted prices in active markets for identical assets or liabilities.
	Level 2. Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3. Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.
	The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of September 27, 2013, and indicates the fair value hierarchy of the valuation techniques utilized to determine such value (in millions):

	Money Market Funds. The Company’s money market funds are funds that invest in U.S. Treasury and U.S. Government Agency securities and are recorded within cash and cash equivalents in the condensed consolidated balance sheets. Money market funds are valued based on quoted market prices.
	Auction-Rate Securities. The Company’s auction-rate securities have maturity dates through 2050, are primarily backed by insurance products and are accounted for as available-for-sale securities. These investments are classified as long-term investments and recorded within other non-current assets in the condensed consolidated balance sheets. Auction-rate securities are valued by a third party using trade information related to the secondary market.
	Foreign Exchange Contracts. The Company’s foreign exchange contracts are short-term contracts to hedge the Company’s foreign currency risk. Foreign exchange contracts are classified within other current assets and liabilities in the condensed consolidated balance sheets. For contracts that have a right of offset by its individual counterparties under master netting arrangements, the Company presents its foreign exchange contracts on a net basis by counterparty in the condensed consolidated balance sheets. For more information on the Company's foreign exchange contracts, see Note 8 below. Foreign exchange contracts are valued using an income approach that is based on a present value of future cash flows model. The market-based observable inputs for the model include forward rates and credit default swap rates.
	In the three months ended September 27, 2013, there were no transfers between levels and no changes in Level 3 financial assets measured on a recurring basis.
	The carrying amounts of cash, accounts receivable, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities. The carrying amount of debt approximates fair value because of its variable interest rate.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Foreign Exchange Contracts	8. Foreign Exchange Contracts
	Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. As of September 27, 2013, the Company had outstanding foreign exchange contracts with commercial banks for British Pound Sterling, Euro, Japanese Yen, Malaysian Ringgit, Philippine Peso, Singapore Dollar and Thai Baht, which were designated as either cash flow or fair value hedges.
	If the derivative is designated as a cash flow hedge, the effective portion of the change in fair value of the derivative is initially deferred in other comprehensive income (loss), net of tax and presented within cash flow from operations. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial to the condensed consolidated financial statements for the three months ended September 27, 2013 and September 28, 2012.
	A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were immaterial to the condensed consolidated financial statements during the three months ended September 27, 2013 and September 28, 2012.
	As of September 27, 2013, the net amount of unrealized losses with respect to the Company’s foreign exchange contracts that is expected to be reclassified into earnings within the next 12 months was $30 million. In addition, as of September 27, 2013, the Company did not have any foreign exchange contracts with credit-risk-related contingent features. The Company opened $1.0 billion and $769 million and closed $1.4 billion and $1.1 billion, in foreign exchange contracts in the three months ended September 27, 2013 and September 28, 2012, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	9. Stock-Based Compensation
	In connection with the acquisition of sTec, the Company assumed all of the unvested RSUs outstanding under sTec’s stock plans as of the acquisition date.  In addition, the Company assumed all of the stock options outstanding under sTec’s stock plans as of the acquisition date with the exception of any unvested, unexercised and outstanding stock options that had an exercise price greater than the merger consideration as defined in the merger agreement. The assumed stock options and RSUs were converted into equivalent stock options and RSUs with respect to shares of the Company’s common stock using an equity award exchange ratio (see Note 11).
	Stock-based Compensation Expense
	During the three months ended September 27, 2013, the Company recognized in expense $21 million for stock-based compensation related to the vesting of options issued under the Company’s stock plans and the ESPP, as compared to $25 million in the prior-year period. The tax benefit realized as a result of the aforementioned stock-based compensation expense was $5 million and $7 million in the three months ended September 27, 2013 and September 28, 2012, respectively. As of September 27, 2013, total compensation cost related to unvested stock options and ESPP rights issued to employees but not yet recognized was $120 million and will be amortized on a straight-line basis over a weighted average service period of approximately 2.3 years.
	During the three months ended September 27, 2013, the Company recognized in expense $21 million for stock-based compensation related to the vesting of awards of RSUs issued under the Company's stock plans, as compared to $14 million in the prior-year period. The tax benefit realized as a result of the aforementioned stock-based compensation expense was $4 million in both the three months ended September 27, 2013 and September 28, 2012. As of September 27, 2013, the aggregate unamortized fair value of all unvested RSUs was $144 million, which will be recognized on a straight-line basis over a weighted average vesting period of approximately 2.0 years. RSUs include performance stock unit awards (“PSUs”). The effect of PSUs was immaterial to the condensed consolidated financial statements in the three months ended September 27, 2013 and September 28, 2012.
	During the three months ended September 27, 2013, the Company recognized in expense $4 million related to adjustments to market value as well as the vesting of stock appreciation rights (“SARs”), as compared to $12 million in the prior-year period. The tax benefit realized as a result of the aforementioned SARs expense was $1 million and $3 million in the three months ended September 27, 2013 and September 28, 2012, respectively. The SARs will be settled in cash upon exercise. As a result, the Company had a total liability of $48 million related to SARs included in accrued expenses in the condensed consolidated balance sheet as of September 27, 2013. In addition, as of September 27, 2013, total compensation cost related to unvested SARs issued to employees but not yet recognized was $8 million and will be recognized on a straight-line basis over a weighted average service period of approximately 0.6 years.
	Stock Option Activity
	The following table summarizes stock option activity under the Company’s stock option plans (in millions, except per share amounts and remaining contractual lives):
		Number			Weighted		Weighted	Aggregate
		of			Average		Average	Intrinsic
		Shares			Exercise		Remaining	Value
					Price		Contractual
					Per		Life
					Share		(in years)
	Options outstanding at June 28, 2013	11.9			$	29.47
	Granted	1.6			68.4
	Assumed in acquisition	0.4			117.41
	Exercised	(0.7	)		30.14
	Canceled or expired	(0.1	)		29.93
	Options outstanding at September 27, 2013	13.1			$	36.77	4.4	$	380
	Exercisable at September 27, 2013	5.9			$	32.6	3.1	$	205
	Vested and expected to vest after September 27, 2013	12.9			$	36.51	4.4	$	377
	If an option has an exercise price that is less than the quoted price of the Company’s common stock at the particular time, the aggregate intrinsic value of that option at that time is calculated based on the difference between the exercise price of the underlying options and the quoted price of the Company’s common stock at that time. As of September 27, 2013, the Company had options outstanding to purchase an aggregate of 11.2 million shares with an exercise price below the quoted price of the Company’s stock on that date resulting in an aggregate intrinsic value of $380 million at that date. During the three months ended September 27, 2013, the aggregate intrinsic value of options exercised under the Company’s stock option plans was $27 million, determined as of the date of exercise, as compared to $55 million in the prior-year period.
	RSU Activity
	The following table summarizes RSU activity under the Company's stock plans (in millions, except weighted average grant date fair value):
		Number			Weighted Average
		of Shares			Grant-Date
					Fair Value
	RSUs outstanding at June 28, 2013	3.6			$	35.82
	Granted	1.3			68.41
	Assumed in acquisition	0.2			62.73
	Vested	(0.9	)		29.73
	RSUs outstanding at September 27, 2013	4.2			$	48.39
	Expected to vest after September 27, 2013	4			$	48.13
	The fair value of each RSU is the market price of the Company’s stock at the date of grant. RSUs are generally payable in an equal number of shares of the Company’s common stock at the time of vesting of the units. The grant-date fair value of the shares underlying the RSU awards at the date of grant was $88 million in the three months ended September 27, 2013. These amounts are being recognized to expense over the corresponding vesting periods. For purposes of valuing these awards, the Company has assumed a forfeiture rate of 3.3%, based on a historical analysis indicating forfeitures for these types of awards.
	SARs Activity
	The share-based compensation liability for SARs is recognized for the portion of fair value for which service has been rendered at the reporting date. The share-based liability is remeasured at each reporting date, using a binomial option-pricing model, through the requisite service period. As of September 27, 2013, 1.0 million SARs were outstanding with a weighted average exercise price of $7.89. There were no SARs granted and all other SARs activity was immaterial to the condensed consolidated financial statements for the three months ended September 27, 2013.
	Fair Value Disclosure — Binomial Model
	The fair value of stock options granted is estimated using a binomial option-pricing model. The binomial model requires the input of highly subjective assumptions. The Company uses historical data to estimate exercise, employee termination, and expected stock price volatility within the binomial model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options granted was estimated using the following weighted average assumptions:
		Three Months Ended
		September 27,		September 28,
		2013		2012
	Suboptimal exercise factor	2.06		1.9
	Range of risk-free interest rates	0.10% to 2.02%		0.17% to 1.04%
	Range of expected stock price volatility	0.31 to 0.50		0.44 to 0.53
	Weighted average expected volatility	0.43		0.49
	Post-vesting termination rate	3.09%		2.08%
	Dividend yield	1.58%		2.58%
	Fair value	$24.00		$15.63
	The weighted average expected term of the Company’s stock options granted during the three months ended September 27, 2013 was 5.0 years, compared to 4.0 years in the comparative prior-year period.
	Fair Value Disclosure — Black-Scholes-Merton Model
	The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the current ESPP are granted on either June 1st or December 1st of each year. ESPP activity was immaterial to the condensed consolidated financial statements for the three months ended September 27, 2013 and September 28, 2012.
	Stock Repurchase Program
	On May 21, 2012, the Company announced that the Board of Directors authorized an additional $1.5 billion for the repurchase of its common stock through May 18, 2017. On September 13, 2012, the Company announced that the Board of Directors authorized an additional $1.5 billion for the repurchase of its common stock and the extension of its stock repurchase program until September 13, 2017. The Company repurchased 2.3 million shares for a total cost of $150 million during the three months ended September 27, 2013. The remaining amount available to be purchased under the Company’s stock repurchase program as of September 27, 2013 was $1.8 billion. The Company may continue to repurchase its stock as it deems appropriate and market conditions allow. Repurchases under the stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Company expects stock repurchases to be funded principally by operating cash flows.
	Dividends to Shareholders
	On September 13, 2012, the Company announced that its Board of Directors had authorized the adoption of a quarterly cash dividend policy. Under the cash dividend policy, holders of the Company’s common stock receive dividends when and as declared by the Company’s Board of Directors. In the three months ended September 27, 2013, the Company declared a cash dividend of $0.25 per share of the Company’s common stock to shareholders of record as of September 30, 2013, totaling $59 million, which was paid on October 15, 2013. The Company may modify, suspend or cancel its cash dividend policy in any manner and at any time.

Acquisition	11. Acquisitions
	Acquisition of sTec
	On September 12, 2013, the Company completed its acquisition of sTec, a provider of enterprise solid-state drives. As a result of the acquisition, sTec was integrated into the Company's HGST subsidiary and became a wholly owned indirect subsidiary of the Company. The purchase price of the acquisition was approximately $336 million, consisting of $325 million which was funded with available cash and $11 million related to the fair value of stock options and RSUs assumed. The Company identified and recorded the assets acquired and liabilities assumed at their estimated fair values at the date of acquisition, and allocated the remaining value of $86 million to goodwill. The values assigned to the acquired assets and liabilities are based on preliminary estimates of fair value available as of the date of this Quarterly Report on Form 10-Q, and may be adjusted as we complete our fair value analyses. Such amounts may be adjusted during the measurement period of up to 12 months from the date of the acquisition as further information becomes available. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in material adjustments to goodwill. The preliminary purchase price allocation was as follows (in millions):
		September 12,

	Tangible assets acquired and liabilities assumed:
	Cash	$	77
	Accounts receivable	12
	Inventories	35
	Other current assets	14
	Property, plant and equipment	44
	Other non-current assets	47

	Accrued liabilities	(22		)
	Other non-current liabilities	(5		)
	Intangible assets	58
	Goodwill	86
	Total	$	336
	In-process research and development of $15 million that is included within intangible assets relates to projects associated with next generation PCIe products. The remaining intangible assets of $43 million primarily relates to existing technology that will be amortized to cost of revenue over the weighted average useful life of 3.5 years.
	The $86 million of goodwill recognized is primarily attributable to the benefits the Company expects to derive from augmenting HGST's existing solid-state storage capabilities and accelerating its ability to expand its participation in the growing area of enterprise solid-state drives ("SSDs"). None of the goodwill is expected to be deductible for tax purposes. The impact to revenue and net income attributable to sTec was immaterial to the Company’s condensed consolidated financial statements for the three months ended September 27, 2013.
	Acquisition of VeloBit
	On July 10, 2013, the Company acquired VeloBit, a privately held provider of high-performance storage I/O optimization software. As a result of the acquisition, VeloBit was fully integrated into the Company's HGST subsidiary and became a wholly owned indirect subsidiary of the Company. The acquisition is intended to build on HGST's strategy to enhance the overall value of datacenter storage by integrating HGST SSDs with software. The impact of the acquisition was not material to the Company's condensed consolidated financial statements.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	13. Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company adopted this pronouncement in the first quarter of fiscal 2014. Since ASU 2013-02 related only to the presentation and disclosure of information, it did not have a material effect on the Company’s condensed consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"). The new standard requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the condensed consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The new standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2013, which for the Company is the first quarter of fiscal 2015. The Company is currently evaluating the impact ASU 2013-11 will have to its condensed consolidated balance sheets.

Subsequent Events [Abstract]
Subsequent Event	14. Subsequent Event
	On October 17, 2013, the Company acquired Virident Systems, Inc. ("Virident"), a provider of server-side flash storage solutions for virtualization, database, cloud computing and webscale applications. Virident is being integrated into HGST, a wholly owned subsidiary of the Company. The acquisition price is estimated to be approximately $685 million and was funded with available cash. The acquisition is expected to further HGST's strategy to address the rapidly changing needs of enterprise customers by delivering intelligent storage solutions that maximize application performance by leveraging the tightly coupled server, storage and network resources of today’s converged datacenter infrastructures. Based upon the timing of the acquisition subsequent to the end of the Company's first quarter of fiscal 2014, the initial accounting for the business combination is incomplete at this time and the Company is in the process of determining the fair values of the net assets acquired and goodwill resulting from the acquisition.
