1前言磁光盘存储器作为可擦除大容量存储器,已由两三家公司推出不具备重写功能的第一代样机,正进入实用化阶段。为使这种存储器进一步提高性能(高数据传递速度、短存取时间),进一步扩大应用范围,必须确立重写技术。本文介绍磁光盘存储器中有代表性的重 1 Introduction Magneto-optical disk memory, as erasable high-capacity memory, has been launched by two or three companies in the first generation of prototypes that do not have rewrite capabilities and is entering the practical stage. In order to further improve the performance of this memory (high data transfer speed, short access time), to further expand the scope of application, rewrite technology must be established. This article describes the typical weight of magnetic disc memory
