ABSTRACT:
A method of generating constant tape tension in a tape transport apparatus of the type in which the supply and take-up reels of tape are simultaneously driven by surface engagement with a driving capstan.
The method involves the utilization of a flexible but relatively inelastic belt around the periphery of resilient capstan material to introduce reel size-related supply and take-up reel velocity adjustments to counteract the similar but opposite velocity adjustments which inherently occur through the use of a resilient capstan and which, if uncompensated, result in undesirable tension variations during the course of the tape transporting operation.
