Patent ID: 8663772

Claim:
An optical recording medium, comprising: a substrate; a light absorption layer on the substrate; and a minute structure on the light absorption layer, wherein the substrate, the light absorption layer, and the minute structure are arranged in the order recited, wherein the minute structure is a recording mark and the minute structure comprises: a sulfur compound; a silicon oxide; and a material for raising an optical absorption ability to a light with a predetermined wavelength, wherein the molar percentage of the silicon oxide in the minute structure is in the range of between 10 mol % and 30 mol %, wherein the minute structure has a diameter in the range of 80-450 nm, wherein the material for raising the optical absorption ability to the light with the predetermined wavelength comprises: at least one of ZnTe, ZnSe or MnS; and a fluorescent material, and wherein the minute structure is a mixture of the sulfur compound, the silicon oxide, and the material for raising the optical absorption ability to the light with the predetermined wavelength.
