摘要 |
<p>A memory (80) stores data concerning errors or differences between commanded number of tracks to be traversed and the number of tracks actually traversed by an optical pickup (20) actuated by a servo controller (30) in accordance with this command. A traversed track number computing unit (62) computes the number of tracks to be traversed by the optical pickup (20) when the same is moved to a track which corresponds to the address where the data to be read is stored. A correction processing unit (64) performs a predetermined correction processing on the computed number of tracks to be traversed, taking into consideration the error data stored in the memory (80). <IMAGE></p> |
