ABSTRACT:
A magnetic tape drive arrangement without pressure roller, having a signal generator which generates a signal T, derived from the capstan motor current and the capstan speed. The is proportional to the instantaneous torque exerted on the magnetic tape by the capstan, which signal T controls the supply and/or take-up motors in such a way that this signal is minimized, so that a slip-free magnetic-tape drive without pressure roller is possible.
