ABSTRACT:
In a rotary head magnetic recording and reproducing system, the number of horizontal synchronous signals which occur between the vertical synchronous signals are kept almost constant by delaying the video signal of the field following the one in which a shift of a track has been detected, the operation occurring when the system is in the abnormal reproducing mode in which the speed of the magnetic tape in the reproducing mode is different from the speed of the magnetic tape in the previous recording mode.
