To form a recording layer capable of ascertaining most suitable absorptiveness, having the recording pit resolution of a laser beam, and high homogeneity in case of carrying out reproduction of information recording in use of a semiconductor laser of a wavelength range of 630-680 nm.
The optical recording medium takes an anthraquinone metallic complex compound expressed by formula as a recording layer. In the formula, R1-R8 show residue moieties of a univalent organic cyclic compound, and at least any one of 1, 4, 5, 8 phases is a hydrogen group. M shows univalent metal such as silver, copper bivalent metallic component such as iron, zinc, nickel, cobalt, manganese, cadmium, tin calcium, magnesium, palladium, or the like, trivalent metal such as aluminum, or vanadium oxide, titanium oxide, aluminum chloride, iron chloride, tin chloride, or the like.
