【Abstract】 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.更多还原
