ABSTRACT:
A method of making a magnetic recording medium by forming a recording layer composed of a ferromagnetic material on a strip-like substrate comprises a first step of applying the ferromagnetic material onto the surface of the substrate, a second step of drying the ferromagnetic material applied on the surface of the substrate, a third step of grinding the surface of the dried recording layer on the substrate, a fourth step of removing process grains clinging to the ground surface of the recording layer, and a fifth step of calendering the surface of the recording layer from which the process grains have been removed.
