<p>A silver alloy reflective film is used in an optical information recording medium and contains Ag as a main component, a total of 1 to 10 atomic percent of at least one selected from Nd, Gd, Y, Sm, La, and Ce, and a total of 2 to 10 atomic percent of at least one selected from Li, Mg, Al, Zn, Cu, Pt, Au, Pd, Ru, and Rh. The reflective film preferably further contains 0.01 to 3 atomic percent of at least one of Bi and Sb and/or 2 to 10 atomic percent of at least one selected from In, Sn, and Pb. An optical information recording medium includes the silver alloy reflective film. A silver alloy sputtering target has the same composition as the silver alloy reflective film.</p> |
