ABSTRACT:
An optical recording medium has a transparent substrate with a recorded pattern formed thereon and a saturable absorption dye containing layer disposed on the recorded pattern and containing at least a saturable absorption dye. The saturable absorption dye has a molecular extinction coefficient .epsilon. of 10.sup.4 or greater at the wavelength of reproducing light, and a relaxation time .tau. in the range of 1 ns.ltoreq..tau..ltoreq. 100 ns. A reflecting layer having a reflectivity of 70% or higher on an air boundary thereof may be disposed on the saturable absorption dye containing layer. The saturable absorption dye containing layer may have such a thickness that substantially minimizes the intensity of reflected light due to interference with respect to the intensity of the reproducing light. The saturable absorption dye may comprise a naphthalocyanine-based dye.
