Wavelength multiplexed optical recording material |
摘要 |
A wavelength multiplexed optical recording material is disclosed wherein a photosensitive material including substituted porphine, such as tetra(pentafluorophenyl) porphine or tetra(4-methoxyphenyl) porphine, is uniformly dispersed into an optically transparent dispersion medium. When such wavelength multiplexed optical recording material is cooled to a temperature of liquid helium and irradiated with a laser beam, a large number of holes of narrow width are formed in an inhomogenous absorption band under the phenomenon of photochemical hole burning. As compared to unsubstituted porphine, the above porphine derivatives give an improved recording sensitivity and narrow hole width.
