摘要： A feed guide mechanism for guiding a reciprocating movable member with a guide member having tabular elastic members forming a guide surface for guiding the reciprocal movement of the movable member on one surface thereof. A piezoelectric member with alternately polarized portions are attached to an opposite surface of the guide member. The piezoelectric member undergoes a polarization so that application of an alternating current produces a standing wave to urge the movable member upward and reduce friction.

摘要： A photodetecting device for use in an optical head comprises a photodetector (20) having a body portion (21) at one surface of which a light receiving surface (21a) is provided and a plurality of lead portions (22) each extending outwardly from the other surface of the body portion (21), and, a metallic substrate (10) having a through hole (12) and a plurality of electrically conductive land portions (13) formed on a first surface of the metallic plate (10) via an insulating layer (11). The lead portions (22) of the photodetector (20) are bent toward the substrate (10). An end portion of the lead portion (22) is connected to the land portion (13). The photodetector (20) is disposed so that the light receiving surface (21a) faces the through hole (12) and a light from the optical head (H) on which a second surface of the substrate (10) is joined arrives at the light receiving surface (21a) through the through hole (12).

摘要： An optical head includes a light source for generating a luminous flux, a polarization beam splitter, an object lens opposed to an appropriate recording medium, and a power monitoring device for monitoring the power of the luminous flux output from the light source. The power monitoring device is adapted to utilize a peripheral portion of the luminous flux. This peripheral portion of the luminous flux is distinct from the portion of the luminous flux that is used for reproducing predetermined information from the recording medium and recording the predetermined information onto the recording medium.

摘要： In an optical head unit, a magnetic circuit is provided on the chassis base of a housing in such a manner that it extends parallel to a radial direction of a disk. A head base is provided over the magnetic circuit in such a manner that it can be reciprocated in the radial direction of the disk. An objective lens holder is supported by the head base in such a manner that the objective lens holder is swingable in the radial direction of the disk through an elastic supporting member such as an elastic hinge and in a focusing direction perpendicular to the surface of the disk through an elastic supporting member such as a leaf spring. A head feeding coil secured to the head base and a focusing coil and a tracking coil mounted on the objective lens holder are coupled to the magnetic circuit in such a manner that they are movable in the radial direction of the disk.
