发明名称 MAGNETO-OPTICAL RECORDING MEDIUM AND METHOD FOR REPRODUCING FROM THE MAGNETO-OPTICAL RECORDING MEDIUM.
摘要 A magneto-optical recording medium and a method for reproducing from the magneto-optical recording medium are disclosed. The magneto-optical recording medium includes a base, a readout layer formed on the base, which has perpendicular magnetization in a temperature range between room temperature and Curie temperature; a transfer layer formed on the readout layer, which is predominant in in-plane magnetization at room temperature, and in which a transition occurs from in-plane magnetization to perpendicular magnetization at a predetermined temperature above room temperature; and a recording layer formed on the transfer layer, which has perpendicular magnetization in a temperature range between room temperature and Curie temperature. According to the present invention, a recording bit with a diameter smaller than that of a spot of a light beam formed on the readout layer can be reproduced. Moreover, since noise can be reduced, an improvement in a signal quality can be achieved. <IMAGE>
