摘要： An objective lens actuator is provided which is equipped with an actuating mechanism for actuating an objective lens mounted on a lens holder of an apparatus adapted to write or read information into or from a recording medium. The actuator moves the lens and its holder in two directions, one direction being substantially parallel to a surface of the recording medium such that the objective lens makes turning motion about a pivot axis oriented substantially normal to the surface of the recording medium and the other direction being vertical, with the lens and holder sliding vertically relative to the pivot axis. The actuator is equipped with at least one parallel driving coil for driving the movable section in the parallel direction and with at least one parallel driving magnetic circuit for imparting a magnetic flux to the parallel driving magnetic circuit. The actuator is arranged such that both drive forces, which are generated as a result of respective actions of electric currents flowing through at least two faces of the parallel driving coil and magnetic fluxes of the parallel driving magnetic circuit, constitute turning forces for turning the objective lens about an axis in the same rotational direction, thereby enhancing driving precision.

摘要： An optical disc clamp mechanism that is capable of selectively playing back either of a compact disc or a mini disc. The clamp mechanism includes a circular disc receiving section for contacting a reference surface of either of the compact disc or the mini disc and further includes a magnetic clamp unit for clamping the mini disc by magnetic attraction with a magnetically attractable member of the mini disc. A first conical or spherical taper cone portion for engaging the center hole of the mini disc is mounted to the disc receiving section and a second conical or spherical taper cone portion for engaging the center hole of the compact disc is mounted to the disc receiving section. The first taper cone portion is located inwardly of the second taper cone portion and protrudes from the second taper cone portion in the axial direction. The magnetic clamp unit further includes a stopper element for preventing detachment of the first and second taper cone portions from the disc receiving section. Accordingly, the optical disc clamp mechanism independently affects the centering of a mini disc and a compact disc to allow either of the discs to be centered.

摘要： A magneto-optical recording and/or reproducing apparatus includes an optical head for providing a light spot for recording, reproducing and erasing of a magneto-optical disc, a magnetic head which is disposed at a position opposing the optical head with the magneto-optical disc therebetween and which provides a magnetic field for recording and erasing while maintaining a substantially constant distance from the magneto-optical disc by effecting a lift obtained by an air flow generated by the rotation of the disc, a loadbeam which has the magnetic head on its one end and serves to provide a force caused by elastic deformation to the magnetic head to thereby be balanced with the lift thus obtained, and a moving mechanism connected to the loadbeam. Approaching or evading the magnetic head to or from the magneto-optical disc can be realized by deforming the moving mechanism.
