Optical recording material, and optical recording medium

Abstract

One object of the invention is to achieve a phase change type optical recording medium having high degree of modulation and recording sensitivity, and another object of the invention is to achieve a phase change type optical recording medium having already stable write/read characteristics at the time of the first overwriting. The optical recording medium comprises a recording layer made up of an optical recording material containing given amounts of In, Ag, Te and Sb. In one Raman spectrum embodiment of the optical recording there are a scattering peak I-1 having a Raman shift in a range of 113 to 117 cm.sup.-1 and a scattering peak I-2 having a Raman shift in a range of 123 to 127 cm.sup.-1, said scattering peak I-2 being larger in half-width than said scattering peak I-1. In another Raman spectrum embodiment, there are a scattering peak II-1 having a Raman shift in a range of 105 to 125 cm.sup.-1 and a scattering peak II-2 having a Raman shift in a range of 140 to 160 cm.sup.-1, said scattering peak II-1 being higher in intensity than said scattering peak II-2.
