发明名称 Super-resolution magneto-optical recording medium using magnetostatic coupling and information reproduction method using the medium
摘要 A magneto-optical recording medium includes a reproducing layer for contributing to reproduction, a recording layer for storing information, and an intermediate layer disposed between the reproducing and recording layers. The intermediate layer magnetostatically couples the reproducing layer and the recording layer in an entire area between the two layers. The reproducing layer has a compensation temperature between room temperature and a Curie temperature thereof. Sublattice magnetizations in the reproducing layer and recording layer are oriented in opposite directions at one of a temperature lower than the compensation temperature and a temperature higher than the compensation temperature, and are oriented in the same direction in the other of a temperature lower than the compensation temperature and a temperature higher than the compensation temperature.
