A magnetic recording medium having a diamond-like carbon (DLC) film added
therein a Group IV element of the periodic table such as silicon,
particularly in the vicinity of the boundary between the magnetic material
and the formed DLC film. Since a DLC having low friction coefficient can
be formed, the centerline average roughness can be reduced to 30 nm or
even less. Accordingly, a magnetic recording medium improved in magnetic
properties and in lubricity can be obtained.
