Readout analysis of multiwavelength optical disks

The readout of photochromic multi-wavelength storage was analyzed, and its model was established in this paper, with the disk reflectivity and the recording information distribution optional. The luminous power of the readout was divide into two parts: the part without the disturbance of other materials and the reading crosstalk. The expressions of them were presented, which were useful for the further analysis of the crosstalk and the crosstalk suppression method.
