Abstract
The present invention is to provide a highly reflective and corrosion-resistant reflective layer film and its sputtering target, particularly a silver alloy metallic film used in common optical discs (such as prerecorded CD, CD-R, DVD-R, CD-RW, DVD-R, and DVD+RW) and its sputtering target, wherein a main metallic alloy (A) comprising cobalt (Co) or manganese (Mn) or both and an auxiliary metallic alloy (B) if desired are added into the silver alloy metallic film. The auxiliary metallic alloy (B) is selected from one or more of gold (Au), palladium (Pd), platinum (Pt) and copper (Cu). These metals constitute a silver alloy material, with which the sputtering target is made, and a highly reflective and corrosion-resistant layer film is made on an optical discs by sputtering process. The composition of silver alloy (% by mass) is 80%-99.99% of silver, 0.01%-5% of main metallic alloy (A), and 0.01%-15% of auxiliary metal alloy (B).
