ABSTRACT:
A magnetic recording and reproducing apparatus having a delay circuit with a plurality of output terminals, one output terminal providing a delayed output video signal for which a delay amount corresponding to a deviation of an H alignment between adjoining record tracks is provided and another output terminal providing another delayed output video signal for which a delay amount corresponding to one horizontal synchronization interval (1H) is provided, and having signal selection switch circuitry which sequentially selects the reproduced video signal to be sent to the delay circuit and which also selects the delayed reproduced video signal during an interval for which an auxiliary head is selected in place of a normal record/playback head in a variable speed reproduction mode, so that a reproduced video signal with continuous H alignment can be secured and video images with a good picture quality can be achieved.
