ABSTRACT:
A system for reproducing a video signal in a slow-motion reproduction comprises at least one rotary head for reproducing and operating to trace a tape on which has been recorded a video signal along tracks extending obliquely to the longitudinal direction of the tape thereby to pick up or reproduce the recorded video signal from the track, a circuit for intermittently driving a capstan motor for rotating a capstan for driving the tape thereby to shift the tape and to stop the tape intermittently in a slow-motion reproducing mode, and a circuit for controlling rotation of said rotary head so that the relative tracing speed of the rotary head relative to said tape becomes the same both at the time of intermittent tape travel and at the time of intermittent tape stoppage in the slow-motion reproducing mode.
