Filed: 1984-07-11
Abstract: PURPOSE:To move surely a stylus and then a track by keeping the polarity of a switching signal at even-number track movement as that before forced movement in case of track forced movement while inverting the polarity for even- number track movement from that before forced movement. CONSTITUTION:When a track moving signal is generated at a time t1, a position control signal is generated from a position control signal generating circuit 18 and a switch 17 is changed over to the position of a terminal (a), which causes to pick up a low frequency component from a low-pass filter 15 and since the stylus 2 is driven by a signal eliminated with an error component, the stylus moves toward the (n+N) track at the stable position in the n-th track. On the other hand, a polarity switching signal from a polarity switching signal generating circuit 9 keeps L level when the track number is an even number. On the other hand, the number is an odd number, the level goes to H level. Thus, the track is moved stably and surely.
