Abstract

A tape drive assembly includes a compact rectangular housing mounting a fixed take-up reel. A removable supply reel is mounted on a pivotable carrier which is adapted to be swung into a closure position on the housing to place the supply reel in operative position adjacent the take-up reel. In such operative position the supply reel is frictionally engaged by an endless drive belt which also frictionally engages the take-up reel so as to drive both reels and cause the tape to be fed therebetween in a path that passes adjacent a read/write head. The drive belt is formed of a viscoelastic material so that it is maintained on its supporting rollers under tension with the supply reel in or out of engagement with it and so that a constant tension is maintained on the drive belt, and hence the tape, at different driving speeds.
