<P>PROBLEM TO BE SOLVED: To provide an translucent reflecting layer for an optical information recording medium, the layer having the transmittance and the reflectance required as a translucent reflecting layer of an optical information recording medium and having favorable chemical stability such as corrosion resistance, aggregation resistance or the like, and to provide an optical information recording medium and a sputtering target for the translucent reflecting layer to be used for an optical information recording medium. <P>SOLUTION: The translucent reflecting layer for an optical information recording medium comprises an Al-based alloy containing at least one kind of element selected from a group composed of Ti, Ta and Cr by 0.2 to 3.0 at.% in total and has excellent durability. The optical information recording medium has the translucent reflecting layer for an information recording medium and the sputtering target for the translucent reflecting layer of an optical information recording medium comprises the above Ag alloy. <P>COPYRIGHT: (C)2003,JPO |
