摘要： By using an existing, relatively inexpensive manufacturing device, micropatterns (e.g. guiding grooves, prepits) having such track pitch and pit pitch that are smaller than the diameter of a light spot are formed more finely. There are provided at least two layers, i.e. (i) a resin substrate and (ii) a depressed part inducing layer made of dielectric material or metal oxide. A light beam is radiated and focused onto the depressed part inducing layer so as to form pit parts and/or guiding grooves on irradiated parts of the resin substrate. The depressed part inducing layer is then removed, so as to expose the pit parts and/or guiding grooves.

Assuming that a diameter of the light beam at a portion where a light intensity of the light beam becomes 1/e.sup.2 of a light intensity of the center of the light beam is L, a track pitch p is arranged such that 0.6.ltoreq.L/p.ltoreq.1.2.

摘要： A transparent substrate of an optical memory is produced by injection molding using a stamper. Grooves and lands are alternately arranged on the optical memory, for tracking of light converged on the optical memory. The groove width is set in the range of 0.3 .mu.m to 0.4 .mu.m and the groove depth is set in the rage of 80 nm to 100 nm. A decrease in the width of a land at each edge is restrained to 0.2 .mu.m in maximum. With such dimensions, even when the track pitch is set to about 1.4 .mu.m, it is possible to obtain a track crossing signal with intensity sufficient for performing an access operation to a target track. Moreover, since the dimensions bring about an improved reflectance at a land, the optical memory achieves an improved C/N and recording density.

摘要： In a method for reproducing an optical disk of the present invention, address information of an optical disk, provided with tracking guides composed of (1) a wobbling groove wobbled in accordance with address information and (2) a normal groove which is not wobbled, is reproduced. The wobbling groove and the normal groove are alternately provided in a radius direction of the optical disk. When carrying out recording and reproducing of the optical disk, three beams composed of one main beam and two sub beams are used. The three beams are projected so that (a) the sub beams are respectively on the wobbling groove and the normal groove and (b) the main beam is on a land between the wobbling groove and the normal groove. The address information is found from reflected light of one of the sub beams. The above arrangement allows respective central portions of the sub beams to track the tracking guides. Therefore, even in the case where the optical disk is tilted or vibrated, the sub beams do not deviate totally off the tracking guides, thereby permitting to stably reproduce the address information.

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。
