Abstract
This invention is to present a magnetic recording medium protective film possessing a metal oxide film on the surface of a magnetic disc substrate, and having a silane monomolecular adsorption film formed on this metal oxide film by chemical adsorption. According to this invention, the monomolecular adsorption film can be formed on the surface of magnetic recording medium without pinhole and in uniform thickness, which may contribute to improvement of the slipping property of the magnetic head, that is, enhancement of the wear resistance, so that a magnetic recording medium of high density, high reliability, and high performance may be realized.
