ABSTRACT:
An optical disk drive is provided with a microcomputer for calculating the number of tracks on an optical disk traversed by an optical pickup in a seek operation and the number of steps to be taken in the seek operation. The number of steps determined in accordance with a signal output by a rotation detector of a feed motor is incremented or decremented depending on a direction in which the optical pickup is translated, and is preset in a counter. In each step of a seek operation, the optical pickup is driven by the feed motor in accordance with the count of the counter.
