<p>An optical disk apparatus according to an aspect of this invention includes an optical processing unit (2) configured to detect reflected light from an optical disk, a signal generation unit (4) configured to generate a focus control signal and a tracking control signal on the basis of the reflected light detected by the optical processing unit, a correction unit (5) configured to correct the signals generated by the signal generation unit on the basis of a correction value adjusted in advance, and an adjustment unit (7,9) configured to readjust the correction value.
Signal processing following a change in the characteristics of the optical pickup or optical disk are thereby improved.</p> |
