We've been in the disk drive industry for 10 years.And year after year we keep getting better. Ourperformance as an industry leader has helped pacethe dynamic growth of the microcomputer industry.Tandon's 5W' double-sided floppy drive revolutionized the industry. And we quickly followedwith the industry's first half-height 8" floppy drive.Our 3W' and SV!" Winchesters have consistently been

VERTICAL INTEGRATION:Because we manufacture most of the componentsin our drives, we get exactly what we want. Whenwe want it. Direct from our own factories. That meansthe tightest control on quality as weil as cost. A sterling example is our proprietary plated media that isused across our entire Winchester product line. l1'sa total dedication to durable design that is uniquely
