AbstractA video reproducing apparatus which controls a revolution speed of the rotary drum to have a variable speed according to the tape transport speed during a special playback, and maintains the inclination angle of the head running locus to be the same as that during a standard playback. The apparatus comprises a capstan servo, a drum servo, a time base corrector, and a control circuit which controls the above elements, thereby displaying a clear picture without noise bars during the special playback modes.
