ABSTRACT:
A disk drive apparatus is disclosed for stabilizing a track jumping operation of an objective lens. The disk drive apparatus includes a detection section for detecting the direction that object lens is being moved by a tracking operation, and a discrimination section for discriminating the direction of the track jumping operation. A track jump movement then performed based on the detection of movement and discrimination of the track jump operation. Therefore, the track jump is stabilized without being influenced by the movement of the objective lens by the tracking operation.
