光学信息记录介质用银合金反射膜,为此的银合金溅射靶,以及光学信息记录介质
摘要：
一种银合金反射膜被用于光学信息记录介质，并包含作为主成分的银、总共1-10原子％的至少一种稀土元素，和总共1-15原子％的选自In、Sn、Al和Mg中的至少一种，其中所述至少一种稀土元素与所述选自In、Sn、Al和Mg中的至少一种的总含量为5原子％或更高。该银合金反射膜优选还包含0.01-3原子％的Bi和Sb中的至少一种。银合金溅射靶具有与该银合金反射膜相同的组成。
摘要（英）：

A silver alloy reflective film is used in an optical information recording medium and contains silver as a main component, a total of 1 to 10 atomic percent of at least one rare-earth element, and a total of 1 to 15 atomic percent of at least one selected from In, Sn, Al, and Mg, in which the total content of the at least one rare-earth element and the at least one selected from In, Sn, Al, and Mg is 5 atomic percent or more. The silver alloy reflective film preferably further contains 0.01 to 3 atomic percent of at least one of Bi and Sb. A silver alloy sputtering target has the same composition as the silver alloy reflective film.
