摘要
信息的可擦重写磁光记录方式克服了磁记录方式信息密度较小的缺点，本文从磁记录原理出发介绍了磁光记录的原理及其近期发展，概述了这两种技术对记录介质的技术要求，并对记录材料的最新进展进行了述评．
The magnetic and magneto-optical recording technologies and their latest development in the world are introduced. The techmical requirements for the above recording technologies and the recent development of the recording materials are reviewed.
