Abstract
Bidirectional tape drive systems have first and second tape drive capstans and first and second tape drives for rotating, respectively, the first and second tape drive capstans. The first capstan is angularly movable relative to the first capstan drive and a first elastic coupling restrains relative angular movement between the first capstan and the first capstan drive. Similarly, the second capstan is angularly movable relative to the second capstan drive and a second elastic coupling restrains relative angular movement between the second capstan and the second capstan drive. In this manner, tape tension is maintained above zero when the bidirectional tape drive changes directions, and excessive tension upon application of the tape assembly to the tape drive is avoided, while tape slack upon removal of the tape assembly from the tape drive is automatically taken up.
