摘要： An optical memory disc includes a glass substrate on which a plurality of concentric circular guide grooves (or a spiral groove) are formed for tracking purposes. A centering plate is secured to the glass substrate in a manner that the center of a circular opening formed in the centering plate is exactly adjusted to the center of the plurality of concentric circular guide grooves (spiral groove). The circular opening formed in the centering plate is utilized to drive the optical memory disc on a turntable. Since the circular opening is not formed directly in the glass substrate, the center adjustment is easily conducted, and there is no possibility that the glass substrate is damaged when the circular opening is formed.

摘要： An optical memory element includes stripe-shaped grooves formed directly on a glass substrate. To manufacture the optical memory element, a resist film is disposed on the glass substrate, and a groove pattern is formed in the resist film. A reactive ion etching is conducted through the groove pattern formed in the resist film so as to form the guide grooves in the glass substrate. After removing the resist film from the glass substrate, a magneto-optical recording layer is formed on the glass substrate.

摘要： A magneto-optical head assembly for a reflection type magneto-optical memory apparatus uses a laser beam for recording, retrieving, and erasing data on a recording medium comprised of a vertical, magnetic, and anisotropic thin film. The light beam emitted from the head assembly is guided to a fixed position on said recording medium. Included are a light detection apparatus for receiving a control signal, and a separate light detection apparatus for receiving a data signal. A beam splitter, to which has been applied a multicoated thin film dielectric body capable of increasing the Kerr rotation angle of the laser beam reflected from the recording medium, is positioned in the optical system through which the laser beam passes.

摘要： Disclosed below is a control device for positioning an optical focus in an optical disc apparatus that records, plays back, and erases any information by irradiating optical beams such as the laser beams onto a recording media composed of magnetic film, wherein the control device is characterized in that; it incorporates a focussing permanent magnet that makes up a closed magnetic circuit, a focussing yoke plate, a focussing yoke, and a focussing device coil installed so that it crosses a focussing magnetic space existing that exists between the focussing yoke plate and the focussing yoke so that the focussing magnetic space can be created in an area close to the recording media which is installed in the closed magnetic circuit. In addition, the optical focus position control device that executes both the tracking and focussing control operations for the optical disc apparatus also includes mechanism that drives the objective lens in the direction of dual axes, i.e., in the vertical (up/down) and horizontal (left/right) directions.
