PHN 9634 15.8.80 ABSTRACT: Magnetic tape drive arrangement without pressure roller. A magnetic tape drive arrangement without pres- sure roller, having a signal generator which generates a signal T, derived from the caostan motor current and the capstan speed, which 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 pos- sible.
