Abstract

A multi-valued photochromic optical disk written by different flux irradiation based on the photon-mode recording property is presented to obtain high density and high speed. A four-valued (2-bit) photochromic storage is carried out by static testing on pyrrl fulgide derivative. A new nondestructive read out method--dual-beam compensation readout--is proposed and discussed.
