摘要： An optical disk has address recording sections each of which has a wobbled part of one of side walls of a groove. Each address recording section is formed by providing convexes of a groove in an adjacent land so as to widen the groove. With the wobbles thus provided in a concavo-convex form, address information is recorded. Besides, the address recording sections thus provided in the grooves are linearly disposed in radial directions of the optical disk. By thus arranging the optical disk on whose grooves and/or lands information is recorded, mixing of wobble frequency components in reproduced information signals does not occur, the sector method is applicable to the optical disk, and information signals of high quality can be obtained.
摘要翻译：光盘具有地址记录部分，每个地址记录部分具有凹槽的一个侧壁的摆动部分。每个地址记录部分通过在相邻的凸台中提供凹槽的凸起来形成，以便加宽凹槽。由于以这样提供的摆动形式为凹凸形式，所以记录地址信息。此外，这样设置在凹槽中的地址记录部分在光盘的径向上线性地设置。通过这样布置记录有槽和/或焊盘信息的光盘，不会发生重放信息信号中的摆动频率分量的混合，扇区方法可应用于光盘，并且可以获得高质量的信息信号。

摘要： An optical recording element comprising a recording medium which includes an information recording area formed at every unit in a non-continuous condition, the recording medium further including sample pits disposed at intervals of a fixed distance for providing basic information about the locations of the recording units in same track. Each sample pit comprises a plurality of pits disposed next to the sequence of the recording units so that the spacing between the pits differs from the spacing between the recording units. At least one of the plurality of pits is a long-sized inclined pit which is inclined at an angle in the range of 6.degree. to 80.degree. to a recording track. A driving system for driving the optical recording element for recording information in the non-continuous recording area or erasing information stored therein with a light beam the output of which is varied as required and checking whether said recording or erasing has been correctly performed, within a very short time in which the light beam passes through the non-continuous recording area. By using the optical recording element in combination with its driving system, the processing speed for reducing, erasing and verifying these functions can be greatly improved and the irradiating position of the light beam at every recording unit can be correctly controlled.

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.
