ABSTRACT:
A capstanless magnetic tape transport system employs supply and take-up motors, the supply motor being employed as a drag motor. The supply motor is controlled to meter tape at a predetermined speed, and the take-up motor is of such design that, in response to a constant voltage applied thereto, it provides constant tension to the tape being metered.
