摘要： An optical pickup device having a semiconductor laser element mounted on a substrate, a photo detector formed on the substrate to receive a laser beam emitted from the semiconductor laser element and an optical element mounted on the substrate to cover the photo detector to branch the direction of optical path of the laser beam, the optical element having its face opposing the semiconductor laser element formed as an inclined face on which a semitransparent reflection film is deposited. The optical path branching optical element is provided with preventing means by which, of laser beams incident on the optical element, a laser beam reflected and/or scattered within the optical element is prevented from irradiating the photo detector.

摘要： An objective lens drive device has a supporting member to which an objective lens is attached. The supporting member is freely translated in a direction parallel to the optical axis of the objective lens and in a plane perpendicular to the optical axis. The supporting member is attached a stationary portion, and a magnetic circuit provided on the supporting member forms a closed magnetic path. A focusing coil and a plurality of tracking coils attached to the focusing coil drive the objective lens in cooperation with the magnetic circuit so that the objective lens is translated in the direction parallel to the optical axis and in the direction perpendicular to the optical axis. The focusing coil and the tracking coils are mounted on the stationary portion so as to oppose the magnetic circuit with a predetermined spacing therebetween.
