摘要：
An optical recording medium having first protective layer, recording layer, second protective layer, and reflective layer, wherein the recording layer contains a phase-change material represented by Formula (1″1), Formula (1-2), or Formula (1-3); the second protective layer contains one selected from zinc oxides, indium oxides, tin oxides, mixtures thereof, and materials Formula (2), and materials Formula (3). Formula (1″1): InαiSbβiX1γi(X1: Ge, Te, Zn, Mn, or mixture thereof, 0.10≦α1≦0.25, 0.65≦β1≦0.80, and 0.04≦γ1≦0.15) Formula (1-2): Gaα2Sbβ2SnY2Ges2X2∈2 (X2: Te, Zn, Mn, In, or mixture thereof, 0.04≦α2≦0.09, 0.56≦62≦0.79, 0.05≦γ2
