Abstract
A tape driving system is adapted to be used in a recording and/or reproducing apparatus having at least one rotating head for tracing tracks on which a video signal has been recorded. The tracks lie obliquely with respect to the tape longitudinal direction. The tape driving system comprises a capstan for driving the tape, a DC motor for driving the capstan, a circuit for forming a pulse-like voltage of a predetermined level over a predetermined interval of time at a given frequency, and a circuit for selectively applying either the pulse-like voltage from the forming circuit or a continuous driving voltage to the DC motor depending on the reproducing mode. The pulse-like voltage is applied to the motor when in a slow motion reproducing mode to intermittently rotate the motor and cause the capstan to intermittently shift the tape.
