Abstract
A magnetic video reproducing apparatus employing a well-known rotational two-head system, a helical scan system and an azimuth system is adapted to make high speed reproduction of a magnetic tape (2) having a video signal recorded in video tracking pitches larger than the width of the reproducing heads and comprises a capstan servo circuit (15) including speed ratio setting circuits (17, 20), a phase control circuit (19) and a speed control circuit (21), wherein the traveling speed of the magnetic tape (2) for high speed reproduction is adapted to be precisely an odd number of times for normal speed reproduction. The speed control circuit (21) is made to accurately control the traveling speed of the magnetic tape (2) to be of the prescribed value. The phase control circuit (19) is made to control the traveling phase of the magnetic tape (2) to be constant.
