PURPOSE:To coincide the reproduction re-start frame with temporary stop start frame and to synchronize immediately, by memorizing address information of the start point of instruction of temporary stop, and by searching the address information and repeating the search until the temporary stop is released. CONSTITUTION:At the time of temporary stop, the address information picked up by a data extract circuit 17 from the demodulation output issued from a demodulator 10 is supplied to a microcomputer 10, and the microcomputer 16 stores the time number which is an address information at the time of issuance of temporary stop instruction to the incorporated memory according to the temporary stop instruction issued from outside, and at the same time it starts counting the time, and supplies drive signal appropriately to mirror drive circuit and motor control circuit. Therefore, at the time of release of temporary stop, reproduction re-start frame will coincide with the frame when the temporary stop instruction was initiated. Also by shortening the time until the search is started, the insynchronized time in the temporary stop is reduced.
