ABSTRACT:
Iron carbide particles are heat treated in a nitrogen atmosphere to form magnetic particles each comprising an iron base core and a carbon base surface. This magnetic particle powder having increased saturation magnetization .sigma.s is mixed with a binder to form a magnetic layer on a substrate, thus providing a magnetic recording medium which exhibits improved remanence Br and reproduces increased outputs.
