Abstract

Paper presents results of own development in the field of organic recording media for working (WERM) and archives (WORM) optical memory. Recording media for working optical memory have been prepared with the use of original thermally irreversible photochromic compounds from diarylethenes and fulgimides as well as polycarbonate as a polymer binder. Using these recording media, refractive and fluorescent methods for nondestructive readout of optical information have been elaborated. Aiming at making recording media for archives optical memory organic compounds (chalcone, diarylethene) which formed fluorescent products during irreversible photochemical reaction under laser irradiation were used. Based on developed photochromic materials samples of three-layer photochromic recording media have been prepared and tested with positive results on the developed optical device. This device includes Nd - laser and provides generation of several harmonics of laser irradiation.
