Abstract
In an operational mode in which the tape should come to a stop at predetermined positions, a braking process, which causes the stopping of a tape at an exact predetermined place, is provided. At the beginning of the braking process, a target waveform is determined in dependence on the tape speed, and the values of the speed are controlled or regulated in accordance with the waveform. Control of a slow motion mode of a video tape can also be provided.
