<p>Accessing method and an apparatus therefor in an optical disc apparatus having an acousto-optic light deflector for deflecting a light spot to a different address or different track on an optical disc are disclosed. An auto-focus signal is held at a constant level for a predetermined period when the acousto-optic light deflector deflects the light spot. Thus, an affect caused by coexistence of a plurality of acoustic frequencies in the acoustic-optic device is eliminated and fast light accessing is attained.</p> |
