Abstract
In a record and/or replay system of the type wherein magnetic tape moves in a loop about a drum which is rotated by a motor to scan transducer gaps across the tape, drum stall conditions are overcome by momentarily reversing the intended rotational direction of the motor when a command is given to rotate the drum in the intended rotational direction but such rotation does not occur because of tape sticktion on the drum.
