光致变色材料在高密度光存储中的应用及发展

Photochromic material in future high density optical storage system

1．引言自1972年荷兰Philips公司推出使用激光记录和重放信息,并播放电视节目的光盘系统以来,光存储技术就以其高密度、大容量、随机存取、可卸盘、不易擦伤、易于携带和低廉的存储价格等优点,迅速占领了数据存储市场,成为信息发布,数据备份,音频、视频、多媒体产品最主要的存储方式之一。

In this paper, we have given a detailed introduction on several main kinds of applications of photochromic material, which people have paid more and more attention on and used as new recording material in future high density optical storage system. We have also given some comments on the main problems existing in these applications, and outlook of this material used in optical storage system.
