を特徴とする光ピツクアツプ。[Claims for Utility Model Registration] A movable substrate is mounted on a fixed substrate so as to be rotatable and movable along its rotation axis, and the movable substrate is separated from the rotation axis as a reading objective. In an optical pickup in which a lens is attached and the movable substrate is rotated and moved in the axial direction by electromagnetic driving means, a magnetic yoke for forming a magnetic circuit in the electromagnetic driving means is mounted on the fixed substrate together with a magnetic material. An optical pick-up characterized by being integrally formed as a cast product.
