PURPOSE:To set a designated address with a resolving power exceeding the level of the resolving power that is obtained by the minimum division of the address information recorded also to a disk, by making use of the synchronizing information accompanied with the program information. CONSTITUTION:The synchronizing information A which is synchronous with a reproduced frame is supplied to a counter 37 from a synchronism detecting part 35. The counter 37 is reset and count the information A. This count result Ca is always compared with an address data D2 at a comparing part 39. The part 39 supplies the coincidence output H2 to a control part 34 when the result Ca is coincident with the data D2. The part 34 receives the H2 while a reproduction operating command PY is fed and supplies the muting release control signal K to a muting circuit 30. Then the circuit 30 releases the muting with the signal K. |
