PURPOSE:To correct out-of-phase of a reproducing signal between tracks, by so constituting that the reproducing signal obtained by scanning extending over plural tracks delays in order by the time of integer times of out-of-phase of the reproducing signal of each track. CONSTITUTION:FM reproducing video signals of heads 1, 2 are inputted to a switching circuit 5 executes switching by synchronizing with a drum pulse. The FM video signal is sent to a delay processing circuit 6, and its delay processing is executed. That is to say, the FM video signal from the head 1 is inputted to an (a) side terminal by a switch S1. This signal is delayed by integer times of each out-of-phase time (alpha) when a switch S3 is switched to (a) (b) (c) (d) (e) at every track moving interval, and is outptted. In this way, a picture signal of 1 field portion, which has corrected out-of-phase of the FM video signal is outputted. This signal is inputted to a luminance and chrominance signal separating circuit 7, and is separated into a luminance signal and a chrominance signal.
