Abstract: A magnetic recording medium comprising a nonmagnetic support, a magnetic recording layer provided on the support which comprises a binder and a ferromagnetic powder dispersed therein, and a monomolecular film or a built-up film provided on the magnetic recording layer. The monomolecular or built-up film comprises a saturated fatty acid having 10-24 carbon atoms and/or its alkali metal salt which is oriented vertically to the plane of the film. A process for the preparation of the same is also disclosed.

Abstract: A magnetic recording medium is described, having improved carrier noise ratio and weather resistance, by controlling the content and the crystal size of iron nitride which contains iron oxide or .epsilon.-Fe.sub.x N (2<x.ltoreq.3).

Abstract: A magnetic recording material is disclosed which is comprised of a single magnetic layer comprised of plate-shaped ferromagnetic particles wherein the plate-shaped ferromagnetic particles are present in greater number in the surface part of the magnetic layer than in the inner part and/or the plate-shaped ferromagnetic particles are aligned such that an average horizontal axis component of the particles with respect to the surface of magnetic layer is larger in the surface part than in the inner part. The location and alignment of the particles make is possible to increase output with short-wave recording.
