<p>In an optical disk apparatus, a position of an objective lens (6) relative to an optical head is sensed by a sensor (30) and a compensation data corresponding to an eccentricity produced due to a rotation of an optical disk (1) is stored in a memory (24). A start position of the objective lens (16) is stored in a position detector (32) when a linear motor (17a) starts to move the optical head (3). The compensation data is read-out in synchronized with the rotation of the optical disk and the start position is corrected by the read-out compensation data. Thus, the objective lens (6) is maintained at the corrected start position.</p> |
