ABSTRACT:
A magnetic recording medium comprises a non-magnetic substrate and a perpendicular magnetic film of Co-based alloy having a large perpendicular magnetic anisotropy having 0.001 to 5% by atom of nitrogen formed directly or through an underlayer on the non-magnetic substrate. A more preferable range of the nitrogen content is 0.01 to 1% by atom.
