Abstract

PURPOSE: To prevent the unpleasnat thing accompanied with the same video and several times repetition of audio, by compulsively sending the stylus when locked group is taken place.
CONSTITUTION: The recording signal of the disc 1 is demodulated into video signal, and the group number of the tracking groove among the bit information picked up at the bit information pick up circuit 4 is read in the read-in circuit 5 for the group number only. This group number is introduced to the stylus skip detection circuit 6 at the next stage, the presence of stylus skip and further the number of grooves for stylus skip is discriminated, and the signal corresponding to the locked group desired for the detection is outputted from the counter 7. This signal is introduced to the locked group release set 9, the pad 33 moves toward inner circumference with the voice coil 32, and the stylus 30 is compulsively pushed to move the groove. Thus, a plurality of tracking operations for the same groove can be avoided.
