    摘要： This invention relates to a magnetic recording medium comprising a magnetic recording film formed on a substrate directly or with a protective layer therebetween, characterized in that a surface treatment layer made of a reaction product of an azide compound is provided on the magnetic recording film, and preferably a lubricative material layer is further provided on the surface treatment layer. The surface treatment agent is covalently bonded to the surface of the magnetic recording film with an aid of nitrene to improve the durability of the magnetic recording film.

    摘要： A magnetic recording medium is prepared by applying a magnetic paint containing at least magnetic particles and a thermally curable binder to a substrate, thermally curing the applied magnetic paint, thereby forming a magnetic film, and impregnating micropores formed in the magnetic film with a lubricant, where the magnetic paint further contains a poly(alkyleneoxide)-grafted binder, and the grafted poly(alkyleneoxide) moiety is thermally decomposed during the thermal curing, thereby forming the micropores in the magnetic film. A large number of micropores having a pore size of not more than 0.1 .mu.m are formed in the magnetic film, and a magnetic disk of high durability with less noises and errors during the recording and reproduction can be obtained.
