| 20090147632 | OPTICAL DISC DRIVE APPARATUS - In an optical disc drive apparatus, when a start time of a tracking pull-in operation is adjusted according to the eccentricity amount of the optical disc, a suitable starting point of the tracking pull-in operation can be always captured and the pull-in operation of the tracking control can be stably performed, without depending on the eccentricity amount of the optical disc. Further, the eccentricity amount and an eccentricity phase are detected from a track zero crossing signal before the tracking pull-in, and an eccentricity compensation signal of the track is added to the tracking control signal. As a result, also in the optical disc with the large eccentricity amount, the tracking pull-in operation can be stably performed. | 06-11-2009 |
