ABSTRACT:
A magnetic recording medium is disclosed, which comprises a substrate having provided thereon a magnetic substance which is composed of an alloy comprising cobalt, phosphorus and at least one member selected from the group consisting of thallium and elements of group Vb of the periodic table, and optionally at least one member selected from the group consisting of nickel and zinc. The magnetic recording medium exhibits a high coercive force, squareness ratio and a high output with a small noise.
