A magnetic recording medium includes a primary coat formed on a non-magnetic base and a magnetic film of a CoP alloy formed on the primary coat, wherein the primary coat is a metal simple substance selected from the group of Cr, V and W or an alloy of two or more of them, and the magnetic film is at least one of the CoP alloys represented by the following formulae, wherein X, Y, Z, a and b denote atomic percent (at %): CoXPYPtZ where Y and Z denote 4</=Y</=11, and 2</=Z</=10, respectively, with the balance being X; CoXPYPtZNia where Y, Z and a denote 5</=Y</=9, 2</=Z</=10 and 5</=a</=35, respectively, with the balance being X; and CoXPYPtZNiaCrb where Y, Z and a and b denote 5</=Y</=9, 2</=Z</=10, 5</=a</=35 and 0<b</=17, respectively, with the balance being X.
