| Zusammenfassung: | In an information recording medium of the present invention, a recording layer (4) and first and second dielectric layers (2,6) are formed on a surface of a substrate (1). In the recording layer, at least one of recording and reproduction is caused by irradiation of light or application of electric energy. The dielectric layers (2,6) are oxide-fluoride-based material layers containing a fluoride of at least one element selected from La and Ce, and one example of at least one of element selected from the group GM. |
