ABOUT PLEXTOR
Plextor is a subsidiary of the Shinano Kenshi Company (SKC), Ltd. SKC’s roots stretch
back to 1918, when it began to manufacture textiles in Japan’s northern prefecture of
Nagano. (Nagano, incidentally, will be the site of the 1998 Winter Olympics.) SKC’s
involvement in the electronics industry started in 1962, when it diversified into the
production of stepper motors for commercial audio products. SKC is now one of the
world’s largest manufacturers of small motors used in hard disks, floppy disks, tape
drives, copy machines, video cameras ---- and your Plextor CD-ROM drive.
