摘要： An optical repeater is provided between terminal stations and amplifies optical signals that have entered via optical fibers in upward and downward directions and outputs the amplified optical signals to optical fibers in respective directions. The optical fiber on the output side of an upward optical amplifier and the optical fiber on the output side of a downward optical amplifier are optically coupled, with a prescribed loss, by a photocoupler. The upward optical signal is looped back to the optical fiber in the downward direction upon being attenuated by, say, 40 dB via the photocoupler, and the downward optical signal is looped back to the optical fiber in the upward direction upon being attenuated by, say, 40 dB, via the photocoupler.

摘要： A magneto-optical recording medium has a recording layer whereon information is magneto-optically recorded. A readout layer is provided on the recording layer. The readout layer has a compensating temperature that is located between room temperature and the Curie temperature. In the readout layer, upon an application of a light beam, the in-plane magnetization occurs at room temperature and a transition from the in-plane magnetization to vertical magnetization occurs as the temperature of the irradiated area of the readout layer rises above a predetermined temperature. By employing this magneto-optical recording medium, with an application of a light beam that is intensity modulated into two levels, only a spot having a temperature not less than a predetermined temperature is involved in the reproduction; therefore, a recorded bit with a size smaller than the diameter of the light beam can be reproduced, thereby greatly increasing the recording density. Further, the level of the reproduced signals is increased, and crosstalk from the adjoining tracks is reduced; thus, information recording and overwriting can be conducted more easily.
摘要翻译：磁光记录介质具有磁信息记录信息的记录层。读出层设置在记录层上。读出层具有位于室温和居里温度之间的补偿温度。在读出层中，在施加光束时，在室温下发生平面内磁化，并且随着读出层的照射区域的温度上升到预定值以上，从面内磁化向垂直磁化的转变发生温度。通过采用该磁光记录介质，通过施加强度调制为两个级别的光束，只有具有不低于预定温度的温度的点参与再现; 因此，可以再现具有小于光束直径的尺寸的记录位，从而大大提高记录密度。此外，再现信号的电平增加，并且来自相邻轨道的串扰减小; 因此，可以更容易地进行信息记录和重写。

摘要： A recording head for a magnetic printer utilizes a so-called magnetography, in which a magnetic latent image formed on a magnetic recording medium is developed and actualized by a magnetic toner and which image is transferred and fixed on a sheet of recording paper to provide a hard copy. The recording head for a magnetic printer includes a first thermal head member, second thermal head member juxtaposed with the first thermal head member with a space therebetween, and a magnetic head member arranged on the first and the second thermal head members. A magnetic gap of the magnetic head member extends immediately above the space between the first and the second thermal head members linearly in the same direction. By this structure, a recording head for a magnetic printer which has simple structure and allows formation of a magnetic latent image having clear boundary between opposite magnetic polarities on a magnetic recording medium, is provided.

摘要： In an optical disk, since a header section has only one recording section for address information, the capacity of memory where a user can freely record data is increased. In an optical disk drive, four laser beams have a fixed positional relation. Based on the address information of a header section read out by at least one of the laser beams and the positional relation among the laser beams, the address information of tracks being scanned by the other laser beams is obtained. It is therefore possible to accurately record or reproduce information on the optical disk.

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： An intermediate layer is formed between a memory layer and a writing layer. The intermediate layer shows in-plane magnetization at room temperature, and perpendicular magnetization within a temperature range within which the coercive force of the memory layer is lower than that of the writing layer. The Curie point of the intermediate layer is lower than that of the memory layer. Like a conventional method, light-intensity modulation overwriting is performed by irradiating laser light whose intensity has been modulated between high level and low level while applying a recording magnetic field after performing an initialization. Even when there are variations in the raised temperature by the irradiation of laser light of high level, it is possible to perform stable overwriting with light-intensity modulation by satisfactorily restraining the exchange forces between the intermediate layer and the writing layer from causing coupling.

摘要： A magneto-optical recording medium includes a first magnetic layer, a second magnetic layer and a third magnetic layer respectively made of rare earth-transition metal alloys. The first magnetic layer has a perpendicular magnetization in a temperature range between room temperature and its Curie temperature. The second magnetic layer has its Curie temperature higher than that of the first magnetic layer, and coercive force thereof at room temperature is nearly zero. The third magnetic layer has a perpendicular magnetization in a temperature range between room temperature and its Curie temperature. The Curie temperature of the third magnetic layer is higher than the Curie temperature of the first magnetic layer. The coercive force of the third magnetic layer at room temperature is lower than that of the first magnetic layer. The compensation temperature of the third magnetic layer is higher than that of the second magnetic layer. Having the above arrangement, an overwriting is permitted on the magneto-optical recording medium, and an initializing magnetic field and a recording magnetic field in a magneto-optical recording and reproducing device are set in the same direction.

摘要： An ink jet head has an ink head main body that is constituted of a substrate, spacers that are formed on one side of the substrate, and a roof plate that is joined to the substrate through the spacers. One or more ink passages are independently formed between the substrate and the roof plate. Rows of piezoelectric devices, each of which is made of a plurality of piezoelectric devices aligned along each ink passage, are formed through the respective ink passages. Ac voltages whose phases are different from each other by 90 degrees are applied to the respective piezoelectric devices. Progressive waves, which are excited by the rows of piezoelectric devices, allow ink to move through the ink passage and to be sprayed.
