磁光盘材料的研究进展

Research Progress of Magneto-Optical Disk Materials

摘要:

概述了磁光记录原理，介绍了磁光盘的基板材料，并重点阐述了稀土－过渡（ＲＥ－ＴＭ）合金非晶膜的制造方法，性能及其保护膜。另外还扼要介绍了氧化物单晶膜，多晶膜和多层超薄磁光记录膜的优缺点，并指出多层膜磁光记录材料是今后的发展方向。

Abstract:

Introduce the principle of magneto-optical recording and substrate materials of magneto-optical disk, specifically the properties,manufscture methods and protective film of the rare earth-transition metal(RE-TM)alloy amorphous film.And simply describes the properties and feature of oxide single-crystal,multi-crystal and multiple-story magneto-optical recording film. It is pointed out that the future developing tendency will be multi-layes magneto-optical recording materials.
