    摘要： Provided are highly reliable information processing equipment enabling a high recording density, and a blue color, blue-violet color and violet color based semiconductor light emitting device operable at a low threshold current density, which device is suitable for the information processing equipment. According to the present invention, there can be realized highly reliable optical information processing equipment enabling high recording density, which is capable of sufficiently recording or reproducing a dynamic image in or from a high-definition TV. An n-type impurity is doped in a barrier layer of a quantum-well active layer of a semiconductor light emitting device at a high density. Alternatively, the oriented plane of a quantum-well active layer of a semiconductor light emitting device is inclined from the (0001) plane, whereby the threshold current value of the semiconductor light emitting device can be reduced. The semiconductor light emitting device is represented by a gallium nitride based compound semiconductor laser device.

    摘要： The optical disk medium permits an increase in recording density using a complex refractive index variation of an inorganic oxide film in a super-resolution medium using an inorganic oxide film. The reflectance of the disk increases due to the complex refractive index variation of the inorganic oxide film. Specifically, in the case where the inorganic oxide film is an oxide film comprising Co, a reflect addition film is provided. The effective spot diameter used for read-out is reduced, thereby increasing recording density. By using a material for which the complex refractive index varies sharply, the recording density can be approximately doubled.

    摘要： A minute optical head is provided so that a light source and one or more photo detector elements are integrated on the same substrate by a simple manufacturing process and may be applied to an apparatus for recording and reproducing recordable optical information. An apparatus for recording and reproducing optical information is arranged to have a minute optical head. A light waveguide layer composed of column semiconductor crystal is formed on a monocrystalline transparent substrate and an active layer is formed on the side of the light waveguide layer. The light beam source is a semiconductor having a vertical resonator formed of a high-reflection film before and after an emitting surface of the active layer so that a light beam is vertically radiated to the substrate. The photo detector element is integrated on the closer portion of the substrate to the light beam source of the semiconductor laser. Further, on the opposed surface of the substrate to the light beam source are sequentially integrated a first transparent layer, a diffraction grating, a second transparent layer, a phase difference generating element, a third transparent layer, a light beam focusing element, a fourth transparent layer, and a slide-resisting protective layer. The slide-resisting protective layer is located closer to and as opposed to the information recording medium.

    摘要： An optical pickup for recording a hologram by using an angle multiplexing method. An optical beam is separated into two beams, a signal beam and a reference beam having different convergence/divergence degrees, by using an optical component such as a diffraction lens. The signal and reference beams are made incident upon the same objective, and the optical component or the objective lens is moved in a direction perpendicular to an optical axis, to thereby realize angle multiplex recording. If an optical information recording medium is inclined, the optical component or the objective lens is moved along the direction along which the optical information recording medium moved to change an angle of the reference beam incident upon the optical information recording medium and compensate for degradation of a reproduction signal.

    摘要： A holographic recording medium in which information can be reproduced by phase conjugate beam without requiring a mirror for obtaining the phase conjugate beam and its driving part and recording density is not reduced. The recording medium includes a recording layer in which an interference pattern is recorded and a light absorption/transmission layer which can be reversibly changed to be in a first state where signal beam and reference beam passed through the recording layer are absorbed at the time of recording of information and a second state where the reference beam is transmitted at the time of reproduction of information, and the reference beam transmitted through the light absorption/transmission layer is reflected by a reflection layer to produce the phase conjugate beam.

    摘要： Provided is a recording and retrieval apparatus for a multi-layer optical disk. A multi-layer optical disk in which a plurality of recording layers and a single servo layer are combined to form a set is used. A spot for the servo layer and a spot for the recording layers are turned on in a time-sharing manner. Servo signal detection areas are formed discretely in the servo layer. The servo signal detection areas and data recording areas are provided so as not to overlap each other when viewed from the spot incident side. Thus, separation of data from each of the layers can be done by even a single photodetector without interference.
