Abstract

A CrTi-based alloy for adhesion film layer and a target material for sputtering, for use in a magnetic recording medium, and a perpendicular magnetic recording medium using the alloy are provided. The alloy is a CrTi-based alloy having a composition formula in an atomic ratio, represented by (Cr, Mo, W)x(Ti, Ta, Zr)wo-x, 40:SX:S70; wherein the Cr element in the alloy is substituted with one or two elements selected from Mo and Win a range of Mo+W: 10 at% to X/2 at%; and the Ti element in the alloy is substituted with one or two elements selected from Ta and Zr in a range of Ta+Zr::,20 at% (including Oat%).
