摘要： An optical disk includes a plurality of disk sheets which are laminated, and each of which has a recording face on one of the surfaces and a flat back surface, wherein the plurality of disk sheets are laminated by adhesive layers in such a manner that between adjacent two disk sheets, a back surface of one of the disk sheets, on the opposite side of the surface where the recording face is formed, faces the disk surface of the other disk sheet. The foregoing structure realizes an optical disk of desirable recording/reproducing characteristics, which is flat and has a fixed interval between recording faces, and which permits the problems of coma aberration, spherical aberration, etc., to be suppressed.

摘要： Grooves and lands are provided to a magneto-optical disk so as to be alternately arranged, and recording bit strings are formed on the grooves and lands respectively so that information is recorded. Moreover, pit rows are formed on boundary sections between the adjoining grooves and lands so that address information of a recording/reproducing track is recorded, and the pit rows are formed every other boundary section. When the grooves and the lands are scanned as the recording/reproducing track by a light, an address of the recording/reproducing track is read out from the pit rows, and successively, discrimination is made whether the recording/reproducing track which is scanned by an optical spot is the groove or the land. This prevents crosstalk which causes inclusion of address information in the next pit rows, thereby, making it possible to obtain accurate address information. Moreover, since a total number of formed pit rows can be decreased and accuracy in a shape of pits is relieved, an optical recording medium can be easily produced.
摘要翻译：将槽和焊盘提供给磁光盘以交替布置，并且分别在沟槽和焊盘上形成记录位串，以便记录信息。此外，凹坑行形成在相邻的凹槽和平台之间的边界部分上，从而记录记录/再现轨迹的地址信息，并且每隔一个边界部分形成凹坑行。当通过光将凹槽和平台作为记录/再现轨道进行扫描时，从凹坑行读出记录/再现轨道的地址，并且依次区分是否由一个光点是凹槽或土地。这防止了在下一个凹坑行中包含地址信息的串扰，从而可以获得准确的地址信息。此外，由于可以减少形成的凹坑排的总数，并且可以减轻凹坑形状的精度，因此可以容易地制造光学记录介质。

摘要： A method of manufacturing a photomask for an optical memory, the photomask having two types of pattern where guide tracks and formatting pits are different in amount of optical transmissions, including the steps of (a) forming on a transparent substrate a thin film of which light transmission amount depends upon its thickness; (b) forming a photoresist film on the thin film; (c) exposing the photoresist film to light with different light intensities depending selectively on the guide tracks or formatting pits; (d) eliminating the photoresist film exposed to the more intense light by the development till the thin film becomes surface; (e) etching the thin film exposed to the more intense light and surfaced; (f) eliminating the photoresist film till the thin film exposed to the less intense light becomes surface; (g) etching away the thin film exposed to the more intense light and surfaced till the transparent substrate becomes surface; and (h) eliminating the remnant photoresist.

摘要： In an optical disk, grooves and lands serving as recording tracks are provided, the grooves are shaped so as to have virtually the same width, and in a first region, the two side walls of each groove wind in accordance with address information. The first region of the groove is formed with its leading portion located at the same angular position as the leading portion of at least one of the first regions of the adjacent grooves. Moreover, the winding portions corresponding to respective bits of the address information are formed in a manner so as to synchronize to the adjacent grooves. With this arrangement, it becomes possible to easily detect address information from the grooves and lands, and consequently to obtain an information reproducing signal with high quality.
