| titleOfInvention | Magneto-optical recording medium and reproducing method thereof |
| abstract | (57) [Summary] [Structure] The recording film 12 includes a read layer GdFeCo and a blocking layer TbF. e, composed of a recording layer TbFeCo. Disk 1 direction 1 When rotated and rotated to 7, the laser light irradiation region 15 has a temperature distribution, and a part of the region is above the Curie point of the blocking layer, and the exchange coupling force between the reading layer and the recording layer can be cut off. In this state, only the magnetization 14 of GdFeCo faces the direction of the external magnetic field 16. Therefore, in the high-density reproduction method of reproducing only the magnetization of the area 18 by adjusting the area where the exchange coupling force is blocked, the same direction as the recording magnetic field is used. A magnetic field is applied to 16 for reproduction. The composition of the recording layer is set so that the compensation temperature is around 100 ° C. [Effect] A reproducing magnetic field is applied in the direction in which the domains exist stably, and by setting the compensation temperature of the recording layer near the temperature at which the domains rise during reproduction, the recording layer can be reproduced with a high coercive force. The domain of can be kept stable. |
