摘要： A magneto-optical recording medium (D1) includes a soft magnetic layer (2) and a magneto-optical recording layer (3) laminated sequentially onto a substrate (1) and is provided with a plurality of grooves (G) and lands (L). The product of the saturation magnetic flux density and thickness of the soft magnetic layer (2) is made different for the respective grooves (G) and lands (L). Thus, with respect to each groove (G) and each land (L), the magnetic focusing effect can be enhanced for one of these with a greater product of saturation magnetic flux density and thickness of the soft magnetic layer (2), while the effect can be weakened for the other one with a smaller product of saturation magnetic flux density and thickness of the soft magnetic layer. This enables the incidence of cross-writing to be suppressed.

摘要： A magneto-optical recording medium capable of perfectly masking a mark adjacent to a mark to be reproduced thereby improving a reproduction output. The magneto-optical recording medium includes a transparent substrate, a magnetic reproducing layer laminated on the transparent substrate, a nonmagnetic intermediate layer laminated on the magnetic reproducing layer, and a magnetic recording layer laminated on the nonmagnetic intermediate layer. The reproducing layer has an easy direction of magnetization in a plane at room temperature, and has an easy direction of magnetization perpendicular to a film surface at a given temperature or higher. The nonmagnetic intermediate layer is thin enough to allow magnetostatic bond between the recording layer and the reproducing layer at the given temperature or higher. Instead of the nonmagnetic intermediate layer, a magnetic intermediate layer having an easy direction of magnetization in a plane from room temperature to its Curie temperature may be interposed between the reproducing layer and the recording layer.

摘要： A magneto-optical recording medium of a three-layered structure (consisting of a readout layer, an intermediate layer, and a recording layer), capable of double-mask magnetically-induced super-resolution readout, has magnetic properties such that the exchange coupled force between the readout layer (a GdFeCo film) and the intermediate layer (a GdFe film) decrease with increasing temperature, while the exchange coupled force between the intermediate layer and the recording layer (a TbFeCo film) increase with increasing temperature. The magnetic property of the readout layer is transition-metal magnetization dominant, and that of the intermediate layer is rare-earth magnetization dominant. When reading the medium, a region (an intermediate-temperature transfer region) where the magnetization in the readout layer is oriented in the direction of magnetization in the recording layer, and a region (a high-temperature rear mask) where the magnetization in the readout layer is oriented in a second specific direction, are simultaneously formed within a beam spot from a state (a low-temperature front mask) in which the magnetization in the readout layer is oriented in a first specific direction, thus achieving a double mask condition in a single step. Overwrite recording and magnetically-induced super-resolution readout are realized on the same magneto-optical recording medium.

摘要翻译：由磁感应超分辨率读出双重掩模的三层结构（由读出层，中间层和记录层组成）的磁光记录介质具有磁性，使得交换耦合读出层（GdFeCo膜）与中间层（GdFe膜）之间的力随着温度的升高而降低，而中间层和记录层（TbFeCo膜）之间的交换耦合力随着温度的升高而增加。读出层的磁特性是过渡金属磁化优势，中间层的磁性优于稀土磁化。当读取介质时，读出层中的磁化在记录层中的磁化方向上取向的区域（中间温度转移区域）以及在记录层中的磁化强度的区域（高温后掩模）读出层在第二特定方向上取向，同时形成在读出层的磁化沿第一特定方向取向的状态（低温前掩模）的光束点内，从而实现双掩模条件在一个单一的步骤。在相同的磁光记录介质上实现重写记录和磁感应超分辨率读出。

摘要： A magneto-optical recording medium having a recording layer made of a bismuth-substituted garnet and deposited by a sputtering over an amorphous substrate of aluminosilicate or borosilicate glass, the recording medium including a garnet underlayer of either a double-layer or single-layer structure. The formation of an underlayer of a double-layer structure made of garnet reduces the level of noise due to light scattering at crystalline boundaries in the garnet film. The formation of an underlayer of a single-layer structure made of a garnet having a lower crystallization temperature than a YIG film is also effective to noise-level reduction. An underlayer has a surface smoothness corresponding to a roughness of approximately 10 .ANG., which is improved from the surface smoothness of a conventional underlayer comprising a YIG film.
