发明名称 Information recording medium and method for producing the same
摘要 An information recording medium which ensures high reliability and favorable overwrite cycle-ability is provided, even when an interface layer is not provided between a recording layer and a dielectric layer. The recording layer and the dielectric layers are formed on the surface of the substrate. In the recording layer, a phase change is generated between a crystal phase and an amorphous phase by irradiation of light or application of an electric energy. The dielectric layers are oxide-fluoride-based material layers containing one or more oxides which each are an oxide of at least one element selected from the group GM consisting of Ti, Zr, Cr, Hf, Nb, Ta, Cr and Si and one or more fluorides which each are a fluoride of at least one element selected from the group GL consisting of La, Ce, Pr, Nd, Gd, Dy, Ho, Er and Yb.
