ABSTRACT:
A control for a digital cassette tape drive maintains constant linear tape velocity at the playback head, constant tape tension, provides compensation for inertial imbalances and provides for minimal stop time. Constant linear velocity is obtained by computing actual velocity at the head and using the computed information to control takeup motor speed. Tape tension control is achieved by energizing the payout hub drive motor with a voltage which is a function of hub rotational speed and motor current.
