Abstract
PURPOSE:To effectively prevent the confusion of the regenerating action of a disk by detecting whether information read with a reader contains industrial music information or not and controlling the output of the information according to the result. CONSTITUTION:When the information containing the industrial music information is recorded on the disk, the information is read by a pickup 1, data- demodulated and corrected 3, D/A-converted 4, and band-limited by an LPF 5. Further, a subcode Q10 separated at an EFM demodulating part 2 is subcode- regenerated 7 and detected at a control data detecting part 8. In this case, when the detecting part 8 connects a muting switch 6 to a terminal A, a signal is outputted from the switch 6. On the other hand, for the disk, on which the information without the industrial music information is recorded, the detecting part 8 detects that the disk is the one to record the information which does not contain any music information from control data and connects the switch 6 to the side of a terminal B. Thus, the signal to pass through the LPF 5 is not outputted to a next step.
