光数据存储的新进展

文章从不同角度全面系统地论述了光数据存储的新进展，一是以存储功能为生长线，着重论述只读存储→可录存储→可直接重写存储等光存储的存储机理和应用现状；二是以存储密度为里程碑，着重阐明CD存储→DVD存储→纳米存储→三维存储等存储密度不断获得数量级提高的物理内含，文章最后指出21世纪光存储技术的发展趋势。

NEW DEVELOPMENT OF OPTICAL DATA STORAGE

The review of optical data memory is presented from different angles. First, from the viewpoint of the storing function, the principles and applications of read\|only, recordable and rewritable memories are discussed. Second, from the viewpoint of recording density, the physical contents of the development from CD, DVD, nanometer recording to 3\|dimensional recording are reviewed. The final part of this paper deals with the future perspective of novel storage in the 21 century.
