Beschreibung
Zusammenfassung:	An information recording medium, comprising: a recording layer which can phase-change reversibly between a crystal phase and an amorphous phase by using an optical means or an electric means, wherein the recording layer comprises at least Ge, Te, M1 (which is at least one element selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Yb and Lu), M2 (which is at least one element selected from the group consisting of Sb and Bi) and M3 (which is at least one element selected from the group consisting of Te and Bi).
