Abstract
In an apparatus which reproduces video signals using rotating heads to scan oblique tracks formed on a tape, the tape is intermittently moved and stopped by a tape capstan motor which is driven by a motor drive pulse. The motor drive pulse is generated at predetermined time intervals corresponding to a predetermined number of tracks for slow-motion reproduction of the recorded video signals. Deviations in the amount of tape intermittently advanced, as measured by a predetermined number of tracks, is avoided by varying the pulse-width or amplitude of the motor drive pulse.
