摘要：An optical information recording medium includes a dielectric layer and an Ag-based reflection layer or an Ag-based metal semitransparent layer adjacent to thedielectric layer. The dielectric layer contains niobium oxide between 50 mol % and 75 mol%, zinc sulfide between 10 mol % and 30 mol %. The dielectric layer further contains an

additive which is at least one of or a mixture of at least two of the following materials:aluminum oxide, tantalum oxide, silicon oxide, cerium oxide, yttrium oxide, hafnium oxideand bismuth oxide. By this structure layers, an Ag-based reflection layer or Ag-basedmetal semitransparent layer can apply to a phase-change optical disc without requiring alayer for preventing the Ag-based layer from sulfurization. An optical informationrecording medium having high productivity can be provided.
