PURPOSE:To execute exact program searching, by utilizing a present reproducing time of music continuously after a designated music number has coincided with a reproducing music number, quick-forwarding a pickup up to a little before the start of music, afterwards, switching its speed to a low speed, and detecting inter-music. CONSTITUTION:A signal detected by a pickup 3 is digitally processed 5, music information is D/A-converted 7 and is sounded from a loud-speaker 8, and also a synchronizing signal servos 9 a motor. On the other hand, a tracking control signal and a focus control signal from the pickup 3 are applied to pickup servo- driving circuit 10, control 11 a feed motor 4 of the pickup 3, and also servos the pickup 3. From a signal of the feed motor 4, a pickup position is detected and is inputted to a program searching circuit 13. On the other hand, the digitally processed 5 signal is processed 6 to a control signal, is inputted to the program searching circuit 13, coincidence of a designated music number and a reproducing music number is detected, the pickup is set to a low speed a little before the start of music, and inter-music is detected. In this way, exact program searching is executed. |
