Abstract
An optical information recording composition suitable for use as a recording layer of an optical information recording medium. The optical information recording composition contains Sb, and one or two elements selected from N and O, and optionally one or more elements M selected from Ge, Te, Bi, Sn, Ag, Au, In, Pb, Pd, Pt, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ta, Ga, Zr, Nb, Mo, Ru, Rh, Hf, W, Re, Os, Ir, Dy and Th. A light beam having a wavelength of 200-800 nm can be used to record information on the optical information recording medium and retrieve information therefrom.
