Income Taxes [Abstract]
Income Taxes	NOTE 16. INCOME TAXES During the three and six months ended October 2, 2011, we recorded income tax expense of approximately $249,000 and $172,000, respectively. During the three and six months ended September 26, 2010, we recorded income tax expense of $27,000 and $152,000, respectively. The income tax expense was primarily due to expenses recorded during the second quarter of fiscal 2012 for foreign taxable income. During the three and six months ended October 2, 2011, the unrecognized tax benefits increased by $0.2 million and $0.4 million, respectively, to $17.1 million as of October 2, 2011. The increase was primarily related to R&D tax credits. If recognized, $14.5 million of these unrecognized tax benefits (net of federal benefit) would be recorded as a reduction of future income tax provision before consideration of changes in valuation allowance for deferred tax assets. Estimated interest and penalties related to the income taxes are classified as a component of the provision for income taxes in the condensed consolidated statement of operations. Accrued interest and penalties was $0.3 million as of October 2, 2011 and March 27, 2011, respectively. Our only major tax jurisdictions are the United States federal and various U.S. states. The fiscal years 2002 through 2011 remain open and subject to examinations by the appropriate governmental agencies in the United States and in certain of our U.S. state jurisdictions.
