ABSTRACT:
A slider-position detector for a disk player having a slider whose friction coefficient is low on a guide rail and for carrying a pickup and capable of moving in radial direction of a disk, which detector comprises a locking mechanism for locking the slider in accordance with a locking signal, and controller for providing a locking signal to the locking mechanism while the disk player is in a stop mode. The controller further detects the movement of the slider and causes the locking to lock the slider only upon the detection of movement of the slider while the disk player is in the stop mode. While reducing unwanted operating noises, the slider-position detector is capable of surely detecting the position of the slider easily moved due to external vibrations.
