ピツクアツプの補正駆動装置。 A lens holder holding an objective lens is movably supported in a focusing correction direction along the optical axis of the objective lens and in a tracking correction direction perpendicular to the optical axis, and the lens holder holds the lens holder in a focusing correction direction. A correction drive device for an optical pickup is equipped with a focusing coil that drives the lens holder in the tracking correction direction, and a tracking coil that drives the lens holder in the tracking correction direction, and a fixed side is provided with a magnet facing each of the coils. The tracking coil and the focusing coil are wound on a common bobbin so as to cross each other, and
A correction drive device for an optical pickup, characterized in that a tracking coil, a focusing coil, and a bobbin around which they are wound are integrally fixed to a lens holder.
