ABSTRACT:
On the occasion of stopping the tape being run at a high speed, a winding radius of the tape supply reel is detected, and a tape deceleration rate is set in response to the detected winding radius. After the tape running speed is decelerated in the deceleration rate up to a preset speed, VL, at which the tape being run can be stopped without damage, the tape is stopped by a brake means. Thereby, the tape can be driven at a higher speed than the speed, VL, without damage, enabling a reduction of time required for a fast forward/rewind operation.
