Magnetic recording medium and process for producing the same.

摘要

A magnetic recording medium comprising: (a) a substrate; (b) an NiO primary layer which is provided on the substrate (a) and in which the plane (200) is substantially oriented in parallel with the surface of the substrate (a); and (c) a Co-containing maghemite film which is provided on the NiO primary layer (b) and in which the plane (400) is substantially oriented in parallel with the surface of the substrate (a), the molar ratio of Co to Fe is from not less than 0.01:1 to less than 0.10:1 and the spacing of the plane (400) is not more than 0.2082 nm (2.082 ANGSTROM ). has excellent oxidiation resistance, corrosion resistance and an appropriate coercive force and can be produced at a temperature lower than 500 DEG C.
