摘要： In an optical head of an optical memory device which records, reproduces or erases information onto or from a recording medium by applying a laser beam to the recording medium, a beam splitter is disposed in an optical path to conduct a portion of the laser beam emitted from a laser device to a light detector. In accordance with a detected value from this light detector, the influence of a stray beam generated in an optical system is removed from a servo error signal.

摘要： A magneto-optical memory device includes a recording medium having a magnetic anisotropy in a direction perpendicular to the main surface thereof. A semiconductor laser is employed in an optical system of the magneto-optical memory device for reproduction purposes. A polarization beam splitter is disposed in the optical system. A multi coated dielectric thin-film is deposited on the reflection surface of the polarization beam splitter in order to establish a desired relationship between the reflection of the P-polarization component and the S-polarization component.

摘要： Disclosed is a new magnetic storage medium including a layer of amorphous material typically GdDyFe whose Curie recording point (e.g., 120.degree. C.) is lower than its crystallization point (e.g., 350.degree. C.) to enable crystallization to cause variations in its optical properties such as transmittance or reflectivity for thermomagnetic writing. Reversible recordings are set up on the amorphous material layer by a thermomagnetic writing technique, for example Curie point writing, while unchangeable or permanent recordings are set up on the amorphous material layer through laser-activated crystallization of the amorphous material layer.

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.

摘要： An optical memory disc medium contains a plurality of guide groove tracks. The guide groove tracks are arranged parallel to each other and they are used for controlling a position of a light beam. There is a land region between the guide groove tracks which is wider than the width of the guide groove tracks as measured in the disc-radial direction. Prepits for providing address information for the guide groove tracks are provided. The prepits are formed on the land regions and interposed between the lateral edges in the disc-radial direction of adjacent parallel guide groove tracks. Each prepit has a width which width is a narrower dimension than the width of each guide groove track as measured in the disc-radial direction.

摘要： A cartridge case for containing a disk-shaped recording medium has a shutter attached slidably thereon. The shutter is U-shaped sectionally and the edge sections where the shutter contacts the surface of the cartridge case are rounded so that friction therebetween is reduced when the shutter slides on the surface of the cartridge case. The cartridge case is provided with a notch and an indentation on at least one of its side surfaces corresponding to protruding pieces in the device into which the cartridge case is inserted such that a sensor in the device can be activated only when a cartridge case compatible with the device is inserted and these protruding pieces properly engage with the notch and the indentation on the cartridge case.
