ABSTRACT:
An improved magnetic recording member comprising a magnetic metallic film having the composition Co.sub.x Cr.sub.y Ni.sub.z wherein x, y, and z are atomic ratios and 0.45.ltoreq.x<1.0; 0<y.ltoreq.0.25; and x+y+z=1. The magnetic metallic film is formed over a Cr film provided on a surface of a non-magnetic substrate.
