摘要： A magneto-optic recording medium having a recording layer which is a magnetic multilayer comprising at least three magnetic layers. Ahead of the reproducing light spot in the travel direction, the magnetic wall of the magnetic layer illuminated by the reproducing light moves toward the center of the light spot to expand magnetic domains; behind the reproducing light spot in the travel direction, the movement of the magnetic wall toward the center of the light spot is suppressed. To suppress the movement, for example, a magnetic layer having specific magnetic characteristics may be formed between a displacement layer and a switch layer.

摘要： A magnetic field H(x) or a reproducing beam L(x) of light whose intensity pattern is different is applied to the recording position of a magneto-optical recording medium, and different information corresponding to the patterns is read out of the same recording position. The function H(x) or L(x) is a password for obtaining the information. Only a person who knows the function can access the specific information recorded on the magneto-optical recording medium. The function H(x) or L(x) is a function such that the magnetic field intensity or the beam intensity is modulated with respect to the recording position (x) in such a manner that the information can be reproduced while magnetic domains are picked up from contiguous domains in the recording region at specific intervals. In addition to the security application, the information can be reproduced n times while a reproducing beam PL/PH, which is subjected to power modulation so as to apply a high power PH with a period n times the recording clock, is being projected to a specific magneto-optical recording medium such that magnetic domain expansion reproduction is possible, thereby improving the reproducing C/N significantly.
摘要翻译：将强度图案不同的光的磁场H（x）或再现光束L（x）施加到磁光记录介质的记录位置，并且从同一记录中读出与图案对应的不同信息位置。函数H（x）或L（x）是用于获取信息的密码。只有知道该功能的人才可以访问记录在磁光记录介质上的特定信息。函数H（x）或L（x）是这样的功能，使得磁场强度或光束强度相对于记录位置（x）被调制，使得可以在拾取磁畴时再现信息从特定间隔的记录区域中的连续域开始。除了安全应用之外，可以再次n次地再现信息，而将经过功率调制以便施加具有n倍于记录时钟的周期的高功率PH的再现光束PL / PH投影到特定的磁光记录介质，使得磁畴扩展再现成为可能，从而显着提高再现C / N。

摘要： The invention relates to a magneto-optical storage medium (200) and specifically a domain expansion storage medium. The medium (200) comprises a magnetic storage layer (107) for long term information storage and a thereto magnetically coupled magnetic reproduction or read-out layer (111), wherein an enhanced magnetic domain may be generated during read out. The magnetic layers (107,111) are separated by a non-metallic or metallic, non-magnetic or magnetic layer (109) and at least one metal layer (201, 203), such as Palladium or Platinum, is located adjacent to the magnetic reproduction layer (111). Preferably this metal layer (201, 203) is located on each side of the magnetic reproduction layer (111). The metal layer(s) (201, 203) provides increased heat dissipation and Kerr effect thereby permitting increased data density of the magneto-optical storage medium (200).

摘要： A read-only optomagnetic disk which comprises at least a supporting base and a magnetic layer formed on it, and is provided with a first group of regions ( alpha 1) (corresponding to pits or marks) which are magnetizable in given directions by the irradiation with a laser beam for reproduction, and a second group of regions ( alpha 0) which are not magnetizable in given directions. One region of the first or second groups is handled as an information unit. The presence of this information unit, the length, or the edge position, represents information. Only when a region ( alpha 1) is positioned in the heat accumulated area (a) in the irradiated spot, the coercive force in it is reduced. Therefore, the magnetization is orientated in a given direction ANd by the influence of an auxiliary magnetic field ANd (heated out). In any other area than the ( alpha 1) in the spot, the magnetism is not orientated in the direction ( ANd ). Even if a region ( alpha 0) is in the heat accumulated area (a), magnetism in the whole spot is not in the given directions. Therefore, it is possible to detect the region ( alpha 1) which is smaller than the diameter of the spot.

摘要： A magnetooptical recording medium comprises a transparent substrate (10), on which are sequentially laminated a protective film (14); a first magnetic film (11) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a second magnetic film (12) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a third magnetic film (13) made of a light rare earth metal, heavy rare earth metal, and transition metal alloy; a protective film (15); and a reflecting film (16). The sandwich of the first, second and third magnetic layers constitutes a recording film (17). The compositions of the first and third magnetic layers contain a large amount of light rare earth metal and have a large Kerr rotational angle in a single wavelength region (400 nm to 700 nm). On the other hand, the composition of the second magnetic layer contains a large amount of heavy rare earth metal and has a property suitable for vertical magnetization. The recording film (17) consisting of the sandwich of the first, second and third magnetic layers has a large Kerr rotational angle as a whole in a short wavelength region, and has a large coercive force. This recording film (17) is sufficiently thin (below 400 Å). When the three-layered sandwich and the reflecting layer (16) are combined with each other, a further greater Kerr rotational angle can be obtained.
