MAGNETO-OPTICAL RECORDING MEDIUM AND MAGNETO-OPTICAL RECORDING DEVICE

摘要

There is provided a magneto-optical recording medium and a magneto-optical recording device which greatly reduce the amount of time and light (electric) energy required for writing and reading of data while maintaining high-density recording and which can reduce the size and energy consumption of the magneto-optical recording device. The magneto-optical recording medium contains a recording layer (23) formed of a photoinduced-magnetic material thin film, and a memory layer (24) formed of a ferromagnetic thin film having perpendicular magnetic anisotropy, wherein the recording layer is subjected to photoinduced magnetization in which magnetism is produced directly through irradiation with light.
