Title: Optical disk device
Inventor: YAMAGUCHI HIROYUKI
IPC: G11B7/095
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To correct the incident angle of a beam without separately providing an optical head with a sensor by respectively detecting reproduction states relating to the inner peripheral side addresses and outer peripheral side addresses of tracks and controlling a tilt in such a manner that the reproduction errors on the inner peripheral side and outer peripheral side within a specified period are made the same number. SOLUTION: A tilt shaft 6 is rotated by a tilt motor 8 and one end of a traversing shaft 4 is moved in a direction perpendicular to the plane of the optical disk 1 by means of a nut piece 7, by which the incident angle of the light beam from the optical head in the radial direction to the optical disk 1 is controlled. A tracking detector 10 sends the detected tracking error signals to a microcomputer 15 via inner peripheral side and outer peripheral side address error detecting circuits 13, 14 by the inner peripheral side and outer peripheral side of the target tracks. This microcomputer 15 counts and compares the inner peripheral side and outer peripheral side address errors respectively by each of three rotation periods of, for example, the optical disk 1 and controls the tilt motor 8 according to the results thereof.
