光学式ピツクアツプ。 The lens holding member that holds the objective lens facing the recording medium is finely movable by a leaf spring in the focus servo direction, which moves toward and away from the recording medium, and in the tracking servo direction, which moves along the recording surface of the recording medium. It is supported and the lens holding member includes:
A focus coil that drives the lens holding member in the focus servo direction and a tracking coil that drives the lens holding member in the tracking servo direction are fixedly provided, and a magnetic circuit that crosses the focus coil and the tracking coil is provided. In the optical pickup, the focus coil is wound into a cylindrical shape and only one is fixed to the lens holding member, and the tracking coil is tightly attached to the side surface of the focus coil on the objective lens side. The magnetic circuit is formed by a yoke having two opposing plate parts, and a magnet that is in close contact with one of the plate parts. The one plate part is interposed inside the cylindrically wound focus coil, and the other plate part is interposed between the focus coil and the objective lens,
An optical pickup characterized by facing a magnet with the above-mentioned focusing coil and tracking coil sandwiched therebetween.
