Abstract
PURPOSE: To permit a linear tracking arm to ascend and descent accurately, by correcting an arm position signal by using the tracking error signal that corresponding to an angle of displacement.
CONSTITUTION: Moving member 4, while moving from a rest position to the end of a disk, detects an inter-music address. Change-over circuit 27 and selecting circuit 31 input the output of stylus tip address calculating circuit 26 and that of end address memory circuit 30 to change-over comparing circuit 28, respectively. Until comparing circuit 28 generates a comparison output, drive control signal generating circuit 32 generates a driving signal to drive a linear motor, so that arm 1 will move to the end position. Every time inter-music gap sensor 17 detects an inter- music gap, change-over circuit 27 is controlled and the address of stylus tip address calculating circuit 26 at that time is stored in a prescribed address in inter-music address memory circuit 29. When a coincidence signal is generated by comparing circuit 28, the motion of arm 1 is stopped.
