徴とする光学式ピツクアツプの補正駆動装置。 A lens holder holding an objective lens facing the optical disk is supported so as to be movable in the optical axis direction of the objective lens and in a direction along the recording surface of the optical disk. In an optical pickup correction drive device that is provided with a focusing coil that exerts a driving force and a tracking coil that exerts a driving force in a direction along the recording surface of an optical disk, the focusing coil is connected to a lens. A focusing magnet is fixed to two opposing sides of the holder and faces each of the focusing coils, and a tracking coil is fixed to the other two sides of the lens holder in a protruding state. A tracking magnet faces each of the tracking coils, and the focusing magnet located near the tracking magnet and the tracking magnet are arranged so that their opposing sides have the same polarity. Features a correction drive device for optical pickups.
