ABSTRACT:
A magnetic recording medium includes an uneven layer, a non-magnetic metal base layer, a magnetic layer and a protective layer which are laminated on a non-magnetic base in the order of description. The uneven layer includes non-magnetic metal deposits containing nitrogen or oxygen, and consists of mutually isolated protrusions having a crystalline phase, which are discretely dispersed on the surface of the non-magnetic base, and a connecting layer having an amorphous phase for filling spaces between the protrusions so as to connect the protrusions with each other.
