<P>PROBLEM TO BE SOLVED: To provide an optical disk device that enables quick adjustment of a relative angle of an optical system relative to an optical disk. <P>SOLUTION: An optical disk device 1, in which an optical disk D is irradiated with a laser beam, includes: an angle adjustment mechanism 25 for enabling adjustment of a relative angle between the radial direction of the optical disk D and the optical axis of an optical pickup 3 radiating the laser beam; and a controller 7 for controlling, after the angle adjustment mechanism 25 is adjusted in such a manner that a specified portion on the optical disk D is irradiated with the laser beam, the angle adjustment mechanism 25 according to the estimated amount of control in the angle adjustment mechanism 25 which is estimated based on the actual amount of control in the angle adjustment mechanism 25 when irradiating the portion other than the specified portion with the laser beam. <P>COPYRIGHT: (C)2012,JPO&INPIT |
