摘要： A hologram recording/reproducing device records information onto a medium by a light beam emitted from a laser light source and passing through a forward path, the forward path having optical components in an area extending from the laser light source to the medium, and reproduces the recorded information by the light beam passing through a backward path, the backward path having optical components in an area extending from the medium to an array light detector. The device includes a spatial-light modulator and a first objective lens disposed in the forward path, and a second objective lens and a polarization-dependent diffraction element disposed in the backward path. The modulator generates signal light and reference light from the light beam emitted from the laser light source, the signal light and the reference light being spatially divided from each other and having a common light path. The first objective lens focuses the signal light and the reference light from the modulator onto the medium. The second objective lens forms a hologram image on the light detector based on reproduction light from the medium. The diffraction element is disposed in a hologram real-image plane and diffracts the reference light incident upon the light detector from the second objective lens.

摘要： An optical pick-up device invention is adapted according to the present invention to reproduce an information signal recorded on a multi-layer optical disc having a plurality of information signal storage layers on which information signals are stored. The optical pick-up device includes a light source for emitting a light beam, an optical means for dividing the light beam emitted from the light source into three separate beams composed of a main beam and first and second side beams and radiating these beams onto the multi-layer optical disc, a main beam-receiving member for receiving the main beam reflected from the multi-layer optical disc, first and second side beam-receiving members for receiving the first and second side beams reflected from the multi-layer optical disc, respectively, and a means for outputting a detection signal indicative of a quantity of light in response to the light quantity received by the main beam-receiving member, the first side beam-receiving member and the second side beam-receiving member. The first side beam-receiving member and the second side beam-receiving member are spaced a given distance apart from the main beam-receiving member so that no interference with the main beam reflected from an unfocused information signal storage layer of the multi-layer optical disc is caused, so that the light beam reflected from the unfocused information signal storage layer of the multi-layer optical disc does not have any influence on function of the device.

摘要： In erasing, electrons are simultaneously injected into floating gates from sources of a plurality of memory cells. Thus, the threshold voltages of the plurality of memory cells are increased. In programming, electrons are emitted from a floating gate of a selected memory cell to a drain. Thus, the threshold voltage of the selected memory cell is reduced.

摘要： In a semiconductor memory device according to the present invention, a conductive layer is formed on a field oxide film in a boundary region on the main surface of a semiconductor substrate. A floating gate electrode, an interlayer insulating film, and a control gate electrode are formed on the semiconductor substrate in a memory cell array region with a gate insulating film interposed therebetween. A gate electrode is formed in a peripheral circuit region with the gate insulating film interposed therebetween. An interlayer insulating film is formed on the conductive layer, the gate electrode, and the control gate electrode. A contact hole is formed at a predetermined position of the interlayer insulating film. An interconnection layer is selectively formed on the interlayer insulating film including the inner surface of the contact hole. According to the present invention, it is possible to prevent formation of a concave portion on the surface of the field oxide film in the boundary region. It is also possible to protect the memory cell array region from an external noise by forming the conductive layer on the field oxide film in the boundary region and by fixing the potential of the conductive layer.

摘要： An optical recording medium has a multi-layer film including a reproducing layer and a recording holding layer, in which, while a readout light is radiated to the optical recording medium for transcribing signals magnetically recorded in the recording holding layer to the reproducing layer, the signals are converted by photomagnetic effects into optical signals which are read. Alternately, an optical recording medium has phase pits formed thereon in accordance with signals and changed in reflectance with temperature, in which, while a readout light beam is radiated to the optical recording medium and the reflectance is changed partially within a scanning spot the readout light beam, the phase pits are read. The track pitch p of pits RP of recording signals in a direction at right angles to the scanning direction of the laser light is set to not more than one-half the spot diameter of the laser light to raise the track density to improve the recording capacity of the recording medium.
