<p>PROBLEM TO BE SOLVED: To provide the method of adjustment of a sled-transfer time influenced by a deck deviation at the time of initialization of an optical disc reproducing device. SOLUTION: A time required for a sled to cross the predetermined number of tracks of an optical disc is detected, and one-track transfer time is calculated from the detected time (S110). The calculated one-track transfer time is compared with a reference one-track transfer time (S112). Then, in accordance with the comparison result, a voltage applied to a sled motor is controlled (S114, S116) to maintain the constant sled transfer time regardless of a deck deviation. With this constitution, a problem that the sled transfer time is varied by the deck deviation is solved and, further, by maintaining the constant sled transfer time regardless of the deck deviation, the deviation of an access time caused by the deck deviation can be reduced and the reliability of a product can be improved.</p> |
