摘要： A magneto-optical recording medium is composed of a base which has a property that a light can be transmitted therethrough, a readout layer formed on the base, which has in-plane magnetization at room temperature, whereas, a transition occurs from in-plane magnetization to perpendicular magnetization as the temperature thereof is raised and a recording layer formed on the readout layer for recording information magneto-optically. A recording and reproducing method and the optical head are designed for the magneto-optical recording medium. By the recording and reproducing method using the optical head, information recorded at high density can be reproduced.

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/再现轨迹进行扫描时，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： An optical tape including an optical recording layer for permitting information to be optically recorded thereon and a light-reflective magnetic layer. The light-reflective magnetic layer which reflects light projected onto the recording layer, also permits magnetic recording or magneto-optical recording to be performed thereon, thereby increasing a storage capacity of the optical tape remarkably. Further, the optical tape is provided with a layer to form guiding grooves for tracking control. The layer to form guiding grooves is made up of ultraviolet-hardening resin, photo-resist, or a photochromic material. For example, in the case of using ultraviolet-hardening resin, after a guiding groove pattern has been exposed by projecting an ultraviolet ray on a layer made up of ultraviolet-hardening resin, the exposed areas harden to form areas corresponding to guiding grooves between those exposed areas. The guiding grooves are formed by removing the areas corresponding to guiding grooves from the layer made up of the ultraviolet-hardening resin. Additionally, along with a guiding groove pattern, an index pattern can also be exposed. The guiding grooves thus formed do not reduce the recording density for information of the optical tape.
摘要翻译：一种光学带，包括用于允许光学记录信息的光学记录层和光反射性磁性层。反射投影到记录层上的光的光反射性磁性层也可以在其上进行磁记录或磁光记录，从而显着提高光带的存储容量。此外，光带设置有一层以形成用于跟踪控制的引导槽。形成导向槽的层由紫外线硬化树脂，光致抗蚀剂或光致变色材料构成。例如，在使用紫外线硬化树脂的情况下，通过在由紫外线固化型树脂构成的层上投射紫外线而引导槽图案露出后，露出的区域变硬，形成与引导槽对应的区域暴露地区。通过从由紫外线固化树脂构成的层去除与导向槽相对应的区域来形成引导槽。另外，与引导槽图案一样，还可以暴露索引图案。如此形成的引导槽不会降低用于光带的信息的记录密度。

摘要： A method to produce a magneto-optical recording medium which includes a readout layer having in-plane magnetization at room temperature and in which a transition occurs from in-plane magnetization to a perpendicular magnetization when temperature rises, and a recording layer for storing information thereon magneto-optically. In the readout layer made of GdFeCo by adding Nd thereto, an amount of Nd to be added changes in a direction perpendicular to its film surface, and an amount of Nd is larger on a light incidence side than on the other side. As a result, even when a laser with a short wavelength is used, high density recording can be achieved as undesirable recording and reproducing operations due to a change in a magnetic interaction is prevented and also deterioration in quality of a reproducing signal is prevented.

摘要： A disc cartridge for freely rotatably accommodating a disc-shaped recording medium, which includes a cartridge casing having a disc chamber defined therein for freely rotatably accommodating the recording medium and also a generally U-shaped access opening defined in one of four sides of the cartridge casing, a lid assembly pivotally supported by the cartridge casing for pivotal movement about a pivot pin in a plane substantially parallel to a plane of the cartridge casing for selectively opening and closing the access opening, and a lid lock means provided between the cartridge casing and the lid assembly for locking the lid assembly in a closed position. The lid lock means includes at least one tubular boss having a through-hole defined therein, and an engagement piece accommodated within the through-hole and separably connected to the tubular boss, a part of the engagement piece protruding outwardly from one of opposite ends of the through-hole and engageable in a hole defined in one of top and bottom walls of the cartridge casing which is adjacent to said one of the opposite ends of the through-hole. That part of the engagement piece is engaged in the hole when the lid assembly is held in the closed position, but the engagement piece may be separated from the tubular boss when an external pushing force is applied thereto through the hole.

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.
摘要翻译：在包括读出层的磁光记录介质中，当温度升高时，其在室温下处于平面内的磁化状态，并且在垂直磁化状态下处于垂直磁化状态的记录层在室温至居里点时，在读出层和记录层之间形成具有面内磁化分量和比记录介质低的居里点的中间层，从而突然改变读出层的磁化状态，外层。由于读出层的磁化状态突然变化，所以高度地进行记录。此外，由于读出层和记录层之间的交换耦合被控制，所以提高了记录特性。

摘要： A magneto-optical recording medium is arranged so that (1) a first transparent dielectric layer, (2) a reproduction layer showing in-plane magnetization at room temperature while showing perpendicular magnetization in response to temperature rise, (3) a second transparent dielectric layer, (4) a recording layer made of perpendicular magnetization film; and (5) a protective layer are laminated on a substrate in this order. The reproduction layer has a thickness of 5 nm to 30 nm, the second transparent dielectric layer has a thickness of 6 nm to 40 nm, and the recording layer has a thickness of 20 nm to 80 nm. It is possible to separately reproduce individual recording bit even when one or more adjacent recording bits exist within the diameter of the light beam converged onto a target recording bit. This is because the information of a recording magnetic domain of a portion showing in-plane magnetization is masked.
