    • A magneto-optical recording medium has a multi-layer magnetic film comprising at least a reproducing layer, a memory layer, and a recording layer which are successively deposited in magnetically coupled relationship to each other. Information is recorded on the magneto-optical recording medium selectively in a first state in which the reproducing layer and the memory layer are magnetized by copying a magnetized condition of the recording layer, with a intensity-modulated light beam of a low intensity applied to the magneto-optical recording medium, or a second state in which the reproducing layer, the memory layer, and the recording layer are magnetized by an external recording magnetic field, with a intensity-modulated light beam of a high intensity applied to the magneto-optical recording medium. Recorded information is reproduced from the magneto-optical recording medium by copying the information from the memory layer to the reproducing layer in a limited high-temperature region which is produced due to a temperature distribution within a spot of a reproducing light beam applied to the magneto-optical recording medium.
    • 磁光记录介质具有至少包括以磁耦合关系彼此沉积的再现层,存储层和记录层的多层磁性膜。 信息被选择性地记录在第一状态中,其中再现层和存储层通过复制记录层的磁化条件而被磁化,其中强度调制的低强度光束施加到 磁光记录介质或其中再现层,存储层和记录层被外部记录磁场磁化的第二状态,其中强度调制的光束被施加到磁光学 记录介质。 通过将信息从存储层复制到再现层,在由限制的高温区域中复制记录的信息,该有限的高温区由于在施加到磁光的再现光束的一个点内的温度分布而产生 光学记录介质。
