PURPOSE:To esnsure a quick and accorate shift to the next channel, by eliminating a labor for such an operation in which it is impossible to proceed to the next channel data unless some correction is given to the operation in a usual state of mode. CONSTITUTION:A read clock for channel data is delivered from a channel reading (clock) circuit 315 provided within a control circuit 201 in order to repreduce a channel. Then the read clock is supplied to a clock input terminal CK of a counter 316 via an OR gate 314. Therefore the count value of the counter 316 changes by (1), and an address deignating input which is changed by (1) is applied to an RAM 317 from the counter 316. Accordingly the channel data are delivered to input terminals IO1-IOn of a play channel data control circuit 318 within the circuit 201 as well as to input terminal I11-Iin of a disk error detecting circuit 313 from output terminals J/01-J/0n. |
