Abstract
An optical disc recording/reproducing apparatus according to the present invention has a CPU which holds the largeness of a driving current supplied from a LD driving circuit to a laser diode in a sample hold circuit of an APC circuit, interrupts a driving signal supplied from the LD driving circuit to the laser diode, and outputs the driving current of the largeness. held in the sample hold part from the LD driving circuit to the laser diode at the end of offset correction by an offset correction mechanism, when an offset is detected by offset detectors, and an offset is corrected by offset correction mechanisms, thereby improving the tracking performance of the servo system and enabling stable control without a malfunction.
