Title: Optical disk device
Inventor: KUWABARA MASAYA
IPC: G11B7/09
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To accurately detect a defect on a recording medium even though the optical output of light beams that illuminate the medium, is changed or the reflected beams of the light beams converged on the medium are changed caused by the difference in the reflectivity of the medium. SOLUTION: An illuminating means 11-g emits light beams toward a disk 10. A band limiting means 17 detects track meandering frequency components that are superimposed on tracking error signals. Then, detection is made to determine whether a converging point of the light beams is located on a defect of the disk 10 or not from the output amplitudes of the means 17 and the output of an address section detecting means 21. Based on the result of the detection, a focus drive switching means 16-f and a tracking drive switching means 16-t are switched to a focus hold driving circuit 14-f output and a tracking hold driving circuit 14-t output to secure a control stability.
