IV.(3)  OTHER INFORMATION

     The Company announced its results for the second fiscal quarter of 1996
on October 26, 1995.  Revenue for the three and six month periods ended
October 1, 1995 exceeded the levels for the corresponding periods in the
prior fiscal year.  However, operating results for the current periods were
below the levels reported for the prior fiscal year due to a decline in gross
margins and an increase in operating expenses attributable in part to the
Company's acquisition of the Disks, Heads and Tapes Business of the Storage
Business Unit of Digital Equipment Corporation, on October 3, 1994.  On
November 8, 1995, the Company announced a restructuring of its high capacity
business, including the businesses acquired in the acquisition.
