Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	Income Taxes The Company recorded a provision for income taxes of $1.4 million and $567,000, respectively, for the three months ended October 30, 2011 and October 31, 2010 and $1.9 million and $2.6 million, respectively, for the six months ended October 30, 2011 and October 31, 2010. The income tax provisions for the three and six months ended October 30, 2011 and October 31, 2010 includes state taxes and foreign income taxes arising in certain foreign jurisdictions in which the Company conducts business. The Company records a valuation allowance against its deferred tax assets for each period in which management concludes that it is more likely than not that the deferred tax assets will not be realized. Realization of the Company's net deferred tax assets is dependent upon future taxable income, the amount and timing of which are uncertain. Accordingly, substantially all of the Company's net deferred tax assets as of October 30, 2011 have been fully offset by a valuation allowance. Utilization of the Company's net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations set forth by Internal Revenue Code Sections 382 and 383 and similar state provisions. Such an annual limitation could result in the expiration of the net operating loss and tax credit carryforwards before full utilization. The Company's total gross unrecognized tax benefit as of April 30, 2011 and October 30, 2011 was $13.9 million. Excluding the effects of recorded valuation allowances for deferred tax assets, $11.7 million of the unrecognized tax benefits would favorably impact the effective tax rate in future periods if recognized. Due to the Company's taxable loss position in previous years, all tax years since inception are subject to examination in the U.S. and state jurisdictions. The Company is also subject to examinations in various foreign jurisdictions, none of which were individually material. It is the Company's belief that no significant changes in the unrecognized tax benefit positions will occur through April 30, 2012. The Company records interest and penalties related to unrecognized tax benefits in income tax expense. At October 30, 2011, there were no accrued interest or penalties related to uncertain tax positions.
