Abstract

Multi-wavelength photochromic storage is a new optical storage with high storage capacity based on photochromic principle. The storage mechanism, system structure and disc structure of multi-wavelength photochromic storage are presented. An experimental system with 3-wavelength lasers used to accomplish 3-wavelength photochromic storage is presented. Experiments on the 3-wavelength photochromic storage system have been carried out. The results show that two materials used in the experiment can be used in 3-wavelength photochromic storage and contrast of the readout signal is high. The results also show that little crosstalk between two materials generates, but a little crosstalk generates irradiated by 780 nm laser and the crosstalk do not affect the recognition of the information stored in the recording layer.
