| 发明名称 | Optical information recording medium and method of recording and/or reproducing therein | ||
| 摘要 | An optical information recording medium 1 is constructed by sequentially layering a reflective layer 11, a protective layer 12, a recording layer 13, a protective layer 14, and a light transmissive protective layer 15 on a substrate 10. As the recording layer 13, a recording layer containing ZnS, SiO2, and Sb as principal components, or preferably, a recording layer expressed by a compositional formula [(ZnS)x(SiO2)1-x]y(SbzX1-z)1-y (where 0<x≦1.0, 0.3≦y≦0.7, and 0.8<z≦1.0 are met and X denotes at least one element selected from a group of Ga, Te, V, Si, Zn, Ta, and Tb) is adopted. | ||
