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.
