Abstract:
A magnetic recording medium comprising (a) a non-metallic substrate, (b) a non-magnetic undercoat film, (c) a magnetic film, (d) a protective film, and (e) an orientation-determining film, which determines crystalline orientation of a film provided directly on the orientation-determining film when subjected to surface-texturing, between the non-metallic substrate and the non-magnetic undercoat film;wherein the orientation-determining film comprises NiPX; wherein X is one or more species selected from the group consisting of Group IIA, IIIA, VIIA, VIII, IB, IIIB, IVB, and VB, other than Ac (actinide)-series elements and X has a melting point of 600-2000Â° C.
