載の光学式ピツクアツプの補正駆動装置。[Claims for Utility Model Registration] (1) An objective lens facing the recording medium is supported by a lens support member, and this lens support member is slightly moved in a direction intersecting the optical axis of the objective lens by a spring on an intermediate frame. The intermediate frame is supported by a spring so as to be able to move slightly in the same direction as the optical axis, and the intermediate frame is supported by a tracking coil that drives the lens support member in a direction crossing the optical axis. In an optical pickup correction drive device that is provided with a focus coil that is driven in the direction of the optical axis and a magnet that faces each of the coils, a fixing piece for fixing the leaf spring is integrated into the intermediate member. 1. A correction drive device for an optical pickup, characterized in that the focus coil is fixed to the fixed piece, and the tracking coil is fixed to a lens support member. (2) A correction drive device for an optical pickup according to claim 1, wherein the focus coil is embedded within the fixed piece. (3) The correction drive device for an optical pickup according to claim 1, wherein the focus coil and the tracking coil have the same shape.
