Abstract:
1. An optical disk apparatus for reproducing information from or recording information to an optical disk, comprising: an optical pickup having an objective lens which converges a laser beam to form a light spot, an actuator which moves said objective lens, and a photodetector which detects reflection light from said optical disk; and a control unit which, based on a tracking error signal generated from signals outputted from said photodetector, drives said actuator so as to control a track jump in which said light spot moves from a land to an adjacent land or from a groove to an adjacent groove, wherein, when said control unit outputs an acceleration signal to carry out said track jump at an area close to outer periphery on said optical disk, said control unit outputs said acceleration signal such that a waiting time is provided after said light spot passes an address information portion, a voltage level of said acceleration signal is set and said acceleration signal is outputted upon elapse of said waiting time so that two address portions are passed by the light spot during said track jump.
