	NOTE 1: BASIS OF PRESENTATION
	Quantum Corporation ("Quantum", the "Company", "us" or "we"), founded in 1980, is a leading expert in scale-out storage, archive and data protection, providing solutions for capturing, sharing and preserving digital assets over the entire data lifecycle. Our customers, ranging from small businesses to major enterprises, trust us to address their most demanding data workflow challenges. We provide solutions for storing and protecting information in physical, virtual and cloud environments that are designed to help customers Be CertainTM they have an end-to-end storage foundation to maximize the value of their data by making it accessible whenever and wherever needed, retaining it indefinitely and reducing total cost and complexity. We work closely with a broad network of distributors, value-added resellers ("VARs"), direct marketing resellers ("DMRs"), original equipment manufacturers ("OEMs") and other suppliers to meet customers' evolving needs. Our stock is traded on the New York Stock Exchange under the symbol QTM.
	The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Quantum and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The interim financial statements reflect all adjustments, consisting of normal recurring adjustments that, in the opinion of management, are necessary for a fair statement of the results for the periods shown. The results of operations for such periods are not necessarily indicative of the results expected for the full fiscal year. The Condensed Consolidated Balance Sheet as of March 31, 2014 has been derived from the audited financial statements at that date, but it does not include all disclosures required by accounting principles generally accepted in the United States for complete financial statements. The accompanying financial statements should be read in conjunction with the audited Consolidated Financial Statements for the fiscal year ended March 31, 2014 included in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on June 6, 2014.
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 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"). ASU 2013-11 requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for an net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 does not require new recurring disclosures. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted ASU 2013-11 prospectively in the first quarter of fiscal 2015. Adoption did not impact our statements of financial position or results of operations.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations and recognition of revenue as the entity satisfies the performance obligations. ASU 2014-09 will become effective for us beginning April 1, 2017, or fiscal 2018. We are currently evaluating the guidance to determine the potential impact on our financial condition, results of operations, cash flows and financial statement disclosures.
	In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period ("ASU 2014-12"). ASU 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. ASU 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. We plan to adopt ASU 2014-12 prospectively in the first quarter of fiscal 2016 and do not anticipate adoption will impact our statements of financial position or results of operations.

REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS [Abstract]	'
REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS	'
	NOTE 2: REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS
	During the fourth quarter of fiscal 2014, we identified an error related to certain allowances recorded for estimated future price adjustments with a cumulative $0.7 million overstatement of revenue and accounts receivable at April 1, 2013. Revenue for the first quarter of fiscal 2014 was $0.1 million overstated as a result of this error. We also identified an error related to straight-line rent expense that had accumulated since fiscal 2006, resulting in a $2.1 million cumulative overstatement of rent expense and total other accrued liabilities and other long-term liabilities at April 1, 2013. General and administrative expense was overstated by less than $0.1 million for the first quarter of fiscal 2014.
	In the fourth quarter of fiscal 2014, we evaluated these errors in accordance with the Securities and Exchange Commission ("SEC") Staff Accounting Bulletin No. 99 and determined that the cumulative impact of the errors was not material to our results of operations, financial position or cash flows in our previously issued financial statements and; therefore, amendments of previously filed reports are not required. However, if the entire correction of the errors had been recorded during the fourth quarter of fiscal 2014, the impact would have been significant to the Consolidated Statement of Operations for the quarter ended March 31, 2014. As a result, we revised our prior period financial statements in accordance with the SEC's Staff Accounting Bulletin No. 108.
	We believe the revisions are not material to the Condensed Consolidated Statement of Operations, Condensed Consolidated Statement of Comprehensive Income or Condensed Consolidated Statement of Cash Flows for the three months ended June 30, 2013.

	We warrant our products against defects for 1 to 3 years. A provision for estimated future costs and estimated returns for credit relating to warranty is recorded when products are shipped and revenue recognized. Our estimate of future costs to satisfy warranty obligations is primarily based on historical trends and, if believed to be significantly different from historical trends, estimates of future failure rates and future costs of repair. Future costs of repair include materials consumed in the repair, labor and overhead amounts necessary to perform the repair. If future actual failure rates differ from our estimates, we record the impact in subsequent periods. If future actual costs of repair were to differ significantly from our estimates, we would record the impact of these unforeseen cost differences in subsequent periods.

LONG-TERM DEBT [Abstract]	'
LONG-TERM DEBT	'
	NOTE 7: LONG-TERM DEBT
	On April 24, 2014, our credit agreement with Wells Fargo ("WF credit agreement") was amended to allow us to use proceeds from the credit agreement to repay our convertible subordinated notes so long as we have a fixed charge coverage ratio of 1.5 and liquidity of $25 million. Our amendment also impacted the available line, maturity date and certain covenants and compliance obligations which are reflected below.
	Under the WF credit agreement, as amended, we have the ability to borrow the lesser of $75 million or the amount of the monthly borrowing base under a senior secured revolving credit facility. The WF credit agreement matures March 29, 2017 so long as an amount sufficient to repay the $133.7 million of 3.50% convertible subordinated notes due November 15, 2015 is available for borrowing under the WF credit agreement or is deposited in an escrow account prior to August 16, 2015. Otherwise, the WF credit agreement matures on August 16, 2015. Quarterly, we are required to pay a 0.375% commitment fee on undrawn amounts under the revolving credit facility.
	The WF credit agreement contains customary covenants, including cross-default provisions, as well as financial covenants. Average liquidity must exceed $15.0 million each month. The fixed charge coverage ratio is required to be greater than 1.2 for the 12 month period ending on the last day of any month in which the covenant is applicable. This covenant is applicable only in months in which borrowings exceed $5.0 million at any time during the month. To avoid triggering mandatory field audits and Wells Fargo controlling our cash receipts, we must maintain liquidity of at least $20.0 million at all times. The fixed charge coverage ratio, average liquidity and liquidity are defined in the WF credit agreement and/or amendments. Certain schedules in the compliance certificate must be filed monthly if borrowings exceed $5.0 million; otherwise they are to be filed quarterly.
	We have letters of credit totaling $1.0 million, reducing the maximum amount available to borrow by this amount at June 30, 2014. As of June 30, 2014, and during the first quarter of fiscal 2015, we were in compliance with all covenants and had no outstanding balance on the line of credit.

RESTRUCTURING CHARGES [Abstract]	'
RESTRUCTURING CHARGES	'
	NOTE 8: RESTRUCTURING CHARGES
	In the first quarter of fiscal 2015, restructuring charges were primarily the result of further consolidating a facility previously used by our manufacturing and service operations. The restructuring charges in the first quarter of fiscal 2014 were largely due to strategic management decisions to outsource our manufacturing operations and further consolidate production and service activities. The types of restructuring expense for the three months ended June 30, 2014 and June 30, 2013 were (in thousands):
			Three Months Ended

			$	498		$	6,915		$	53		$	7,466
	The severance and benefits restructuring costs for the three months ended June 30, 2014 was primarily due to right-sizing our sales workforce with our operating plans, and the facilities restructuring costs were primarily the result of further consolidating production and service locations. We anticipate $0.4 million of severance and benefits and the other restructuring accrual will be paid by the end of fiscal 2015 and the remaining $0.1 million of severance and benefits will be paid by the end of fiscal 2016. Facility restructuring accruals will be paid in accordance with the respective facility lease terms.

	Stock Incentive Plans - Grants and Fair Value
	Stock Options
	No stock options were granted during the first quarter of fiscal 2015 or 2014. The Black-Scholes option pricing model is used to estimate the fair value of stock options.
	Restricted Stock
	The fair value of restricted stock units ("RSUs") granted is the intrinsic value as of the respective grant date since the RSUs are granted at no cost to the employee. The weighted-average grant date fair values of RSUs granted during the first quarter of fiscal 2015 and 2014 were $1.21 and $1.32, respectively.
	Stock Purchase Plan
	Under the Stock Purchase Plan, rights to purchase shares are typically granted during the second and fourth quarter of each fiscal year. No rights to purchase shares were granted during the first quarter of fiscal 2015 or fiscal 2014. The Black-Scholes option pricing model is used to estimate the fair value of rights to acquire stock granted under our Purchase Plan.

	NOTE 10: INCOME TAXES
	Income tax provision for the first quarter of fiscal 2015 and 2014 was $0.2 million and $0.4 million, respectively, and reflects expenses for foreign income taxes and state taxes. We have provided a full valuation allowance against our U.S. net deferred tax assets due to our history of net losses, difficulty in predicting future results and our conclusion that we cannot rely on projections of future taxable income to realize the deferred tax assets. Significant management judgment is required in determining our deferred tax assets and liabilities and valuation allowances for purposes of assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support a reversal or decrease in this allowance. Future income tax expense will be reduced to the extent that we have sufficient positive evidence to support a reversal of, or decrease in, our valuation allowance.

LEGAL PROCEEDINGS	'
	NOTE 12: LEGAL PROCEEDINGS
	On February 18, 2014, Crossroads Systems, Inc. ("Crossroads") filed a patent infringement lawsuit against Quantum in the U.S. District Court for the Western District of Texas, alleging infringement of U.S. Patents 6,425,035 and 7,934,041. An amended complaint filed on April 15, 2014 also alleged infringement of U.S. patent 7,051,147. Crossroads asserts that we have incorporated Crossroads' patented technology into our StorNext QX and Q-Series lines of disk array products, and into our Scalar libraries. Crossroads seeks unspecified monetary damages and injunctive relief. Crossroads has already dismissed all claims of infringement with respect to the StorNext QX and Q-Series products. We do not believe it is reasonably possible that we will pay material damages related to this lawsuit.

	In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 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"). ASU 2013-11 requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for an net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 does not require new recurring disclosures. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted ASU 2013-11 prospectively in the first quarter of fiscal 2015. Adoption did not impact our statements of financial position or results of operations.

	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations and recognition of revenue as the entity satisfies the performance obligations. ASU 2014-09 will become effective for us beginning April 1, 2017, or fiscal 2018. We are currently evaluating the guidance to determine the potential impact on our financial condition, results of operations, cash flows and financial statement disclosures.
	In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period ("ASU 2014-12"). ASU 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. ASU 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. We plan to adopt ASU 2014-12 prospectively in the first quarter of fiscal 2016 and do not anticipate adoption will impact our statements of financial position or results of operations.
