摘　　要：多波长光致变色存储是基于光致变色原理的一种高容量光存储方法 .介绍了多波长光存储的存储原理、系统构成和光盘结构 .利用三波长光致变色存储实验装置 ,进行了三波长光致变色存储的实验 .结果显示 ,实验中采用的三种光致变色材料可用于多波长存储 ,多波长存储读出信号对比度较高 ,各记录信号之间几乎无串扰 .记录信息经Multi-wavelength photochromic storage is a new optical storage method with high storage capacity based on photochromic principle. The storage mechanism, the sy stem structure and disc structure of multi-wavelength photochromic storage are presented. Three-wavelength photochromic storage experiment on a three-wavelen gth photochromic storage system is carried out. The results show that three mate rials used in the experiment can be used in multi-wavelength photochromic stora g e and the contrast of the readout signal is high and little crosstalk is generat ed. The contrast of the readout signal remains high after low-speed reading ou t 50 times.
