Abstract
A tape transport mechanism that senses the end of a tape while minimizing but not eliminating back tension at the tape-feeding end. Excessive back tension causes uneven transport in fast forward or rewind. Insufficient back tension causes slack that makes sensing the end of a tape impossible. Both result from keeping the torque identical on both takeup and feed reels. The mechanism automatically switches the torque as the tape reverses so that the takeup reel always has a higher torque than the feed reel, thereby insuring that the tape end is sensed and that tape transport is even regardless of speed.
