ABSTRACT:
In a magnetic disk recorder, a displacement of recording timings of a video signal and a timebase-compressed audio signal on a master disk can be corrected on a slave disk. When an output of a master disk reproducing apparatus is a video signal, a vertical synchronizing signal from a synchronizing separating circuit is delayed by a delay time of substantially 7H (H is the horizontal period) and supplied to a phase servo circuit in a slave disk recording apparatus as a reference signal, while when the output of the master disk reproducing apparatus is the timebase-compressed audio signal, a start flag signal accompanying with the timebase-compressed audio signal is detected by a flag detecting circuit and the start flag signal thus detected is employed as a pseudo vertical synchronizing signal, which is supplied to the phase servo circuit in the slave disk recording circuit as a reference signal.
