磁光盘多重记录方式的研究 　　在未来的电视中，需要容量大而存取速度快的存储器件。文章论述了对磁光盘的现状和记录容量的预测。要使磁光盘大容量化有两种方法，即缩小位尺寸以提高面记录密度的方法和增加记录层数在深度方向进行多重记录的方法。介绍了用柘榴石三层膜进行多 Research on Multiple Recording Methods of Magneto-Optical Discs In future TVs, storage devices with large capacity and fast access speed are needed. The article discusses the status of the magneto-optical disk and recording capacity prediction. There are two ways to increase the capacity of a magneto-optical disk: a method of reducing the bit size to increase the surface recording density and a method of increasing the number of recording layers to perform multiple recordings in the depth direction.
