摘要： An erasing beam B1 and a recording beam B2 emitted from a laser diode array 20 are focused on different tracks of a optical magnetic disk D, the erasing beam B1 being focused on a track located ahead of a track on which the recording beam B2 is focused. The reflected beams of the erasing beam B1 and the recording beam B2 are separated respectively into two polarized components by means of a polarized beam splitter 17 and the polarized components are received by photo sensor means 23 and 24. Based on outputs of the photo sensor means 23 and 24, an address signal, a focus error signal and a tracking error signal are obtained. At the time of reproduction, the laser diode array 20 emits a reproducing beam so that the photo sensor means provide a reproducing signal.

摘要： A magneto-optic disk and a recording/reproduction device therefor adopt optical super-resolution to increase recording capacity. More specifically, the magneto-optic disk has an heat emitting layer (6) on a recording layer (4) and still preferably has an intermediate layer (8) between a reproduction layer (3) and the recording layer (4). The recording/reproduction device includes a circuit (33) for pulsing a laser beam to be radiated to the magneto-optic disk and still preferably includes a polarization rotating unit (50) and a polarizing filter (51) for blocking only the center of the laser beam in reproduction. The heat emitting layer (6) diffusing any heat generated by the laser beam, and the discontinuously radiated laser beam allow small recording domain. The laser beam having its center blocked forms smaller main lobe due to diffraction effect.

摘要： In magneto-optical recording medium, on a transparent substrate of polycarbonate resin, an SiN film having the thickness of 600 to 800 .ANG. and surface roughness Rmax of at most 10 nm is formed. On the SiN film, a GdFeCo reading layer having the thickness of 800 to 1200 .ANG. with Gd content of 30 to 36 at. % and Co content of 12 to 50 at. % is formed. On the reading layer, a TbFeCo recording layer of which Co content is 10 to 16 at. % is formed. The recording layer is a perpendicular magnetization film, and the reading layer is an in-plane magnetization film. At the time of reading, the reading and recording layers are heated, and the direction of magnetization of the recording layer is transferred to the reading layer only in the prescribed heated area. Information can be read only from the transferred portion, and thus a super resolution effect is obtained. When Kerr rotation angle .theta..sub.K is measured for the light reflected from the reading layer while the temperatures of the reading and recording layers are elevated, .theta..sub.K is approximately in proportion to Cth power of the elevated temperature t, wherein C is at least 8.0.

摘要： In a liquid crystal display device having a direct-lighting backlight using LEDs as a light source, the number of LEDs is reduced without causing unevenness in brightness. An LED is disposed under a cylindrical lens to be closer to one end of the lens than a middle part of the lens. Light emitted from the LED is outputted, as diffused light, upward from an end diffusion surface of the lens. A portion of the top surface of the lens makes up a total reflection surface to reflect light emitted from the LED and thereby cause the reflected light to head for the other end of the lens. Diffusion surfaces formed on the top surface and the bottom surface of the lens radiate diffused light upward of the lens, causing uniform light to be radiated from the whole top surface of the lens.

摘要： A scheduling method for use with a multi-thread system which is capable of time-sharing processing a plurality of threads is provided which can avoid the drawback of priority inversion, minimize the modification of a wait queue, and ensure the optimum use of the processing time of a CPU. According to the present invention, a time slot data is assigned to each thread and the scheduling is carried out on the basis of the time slot data. As a processing time is imparted to the time slot data, the execution of the thread to which the time slot data is assigned is started. In case that a higher priority thread has to wait for the completion of the execution of a lower priority thread, the time slot data assigned to the higher priority thread is handled as a time slot data of the lower priority thread, hence allowing the execution of the lower priority thread to be started upon a processing time imparted to the time slot data.
