Abstract

PURPOSE:To stabilize the operation of a synchronizing signal detecting circuit to improve the effect of synchronizing signal extraction, by making the width of recording area on a track integer multiple of the cycle of the synchronizing signal. CONSTITUTION:When a case where the gap is set four times wider than the cycle of a synchronizing signal is considered as an example in the figure, the signal (h) is a reproduce signal and the block No.n is the last block of the previous area, and then, the block No.1 is the first block of the next area. The signal (i) is a gate signal and the (D) is a gate pulse produced by the previous synchronizing signal and the (E), (F), (G), (H), and (I) are gate pulses produced by the (K) of the signal (j). That is to say, gate pulses whose cycles are equal to the cycle of the synchronizing signal are repeatedly produced by using the timing of (K) as a reference. The (L) is obtained by extracting the synchronizing signal extracted from the block No.1 from the (I) of the gate signals. In the same way, synchronizing signals are continuously extracted when synchronizing signals (N), (O), (P), and (Q) are recorded during the gap period of the reproduced signal (k).
