Abstract
A magnetic tape reproducing apparatus in a rotary head VTR is arranged such that when reels are rotatably driven to perform a cue play and a review play, the speed of a motor driving the reels is controlled by a speed control of the motor itself and in accordance with a control signal reproduced from a magnetic tape, thereby making the speed of the magnetic tape approximately constant during the cue play and the review play.
