Patent ID: 7535809

Claim:
An optical disk apparatus capable of drawing a visible image on an optical disk by irradiating a laser beam onto the optical disk, the apparatus comprising: a rotating section arranged to rotate the optical disk; a detecting section arranged to detect a rotating state of the optical disk; an optical pickup arranged to irradiate the laser beam onto the optical disk which is rotated by the rotating section, so that the visible image is drawn on the optical disk; a feeding section arranged to feed the optical pickup in a radial direction of the optical disk; and a tracking control section arranged to control an irradiating position of the laser beam relative to the optical disk, wherein the tracking control section fixes the irradiating position of the laser beam at a first position in the radial direction of the optical disk during a rotation of the optical disk, and shifts the irradiating position of the laser beam by a first distance in the radial direction based on the detected rotating state to a second position at which the irradiating position of the laser beam is fixed during another rotation of the optical disk, and wherein the feeding section feeds the optical pickup in the radial direction by a second distance when the detecting section detects that the optical disk has rotated a predetermined number of rotations, wherein the predetermined number of rotations is greater than one rotation.
