Beschreibung
Zusammenfassung:	A recording layer for an optical data recording medium according to one embodiment of the present invention makes it possible to record an information signal by irradiation with laser beam. The recording layer for an optical data recording medium comprises metal oxides including a Mn oxide, a W oxide, and a Sn oxide. The atomic ratio of Mn with respect to the total number of atoms of metal elements constituting the metal oxides is 3-40 atm %.
