摘要： A magneto-optic memory device which comprises a recording medium deposited by sputtering on a substrate such as glass, a transparent dielectric film formed on the recording medium, and a reflecting film deposited on the transparent dielectric film. This arrangement prevents the recording medium from being oxidized, and stabilizes coercive force characteristics and information recording characteristics of the recording medium.

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： 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 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 recording units in the 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： In a magneto-optical recording medium including a reading-out layer, which is in an in-plane magnetization state at a room temperature and in a perpendicular magnetization state when the temperature rises, and a recording layer, which is in a perpendicular magnetization state at a room temperature to a Curie point, an intermediate layer having in-plane magnetization component and a lower Curie point than the recording medium is formed between the reading-out layer and the recording layer so as to abruptly change magnetization state of the reading-out layer. Since magnetization state of the reading-out layer is abruptly changed, recording is carried out highdensely. Moreover, since exchange-coupling between the reading-out layer and the recording layer is controlled, a recording characteristic is improved.
