Abstract

PURPOSE:To inexpensively obtain good magnetic characteristics by using metallic films consisting of alloys of Fe and Ti to constitute a soft magnetic film and perpendicularly magnetized film, a protective film and the perpendicularly magnetized film, and the protective film, the soft magnetic film and the perpendicularly magnetized film on a substrate. CONSTITUTION:This recording medium is constituted of the soft magnetic film 3 and the perpendicularly magnetized film 2, the protective film 1 and the perpendicularly magnetized film 2, as well as the protective film 1, the soft magnetic film 3 and the perpendicularly magnetized film 2 by using the same metallic films consisting of the alloys of Fe which is ample in resources and inexpensive and Ti which is highly resistant to corrosion and inexpensive. The Ti compsn. is confined to a 15-21atom.% range. The production of the perpendicular magnetic recording medium consisting of the alloys of the Fe system more inexpensive than the conventional perpendicular magnetic recording medium consisting of the alloys of a Co system is thereby enabled and the good magnetic characteristics and recording and reproducing characteristics are obtd.
