Abstract: A playback device has a head provided on a rotary drum to read signals recorded on a tape to produce a playback signal, and a playback signal processor for processing the playback signal. The playback device also includes a timing generator for generating a sync signal used in a varied-speed playback in which playback is performed at a speed different from a speed used for normal playback; a selector for selecting the sync signal between one for the normal playback and one for the varied-speed playback; and a drum rotation controller using the sync signal generated by said timing generator as a reference signal for the rotation of the rotary drum during varied-speed playback. With the above configuration, the vertical and horizontal sync signals supplied to the monitor are maintained to have a constant period. As a result, the resultant images on the monitor are free from disturbances, and it is possible to avoid muting.
