ABSTRACT:
Fillers are mixed into a resin solution used to form a resin layer on the substrate of a magnetic disk. Therefore, the distance from the boundary between the resin layer and magnetic film to the filler top as well as the distance from the surface of the magnetic film to the top of the filler in the magnetic film are freely adjustable by appropriately setting the particle size of mixed fillers, thickness of the resin layer and thickness of magnetic film independently or in combination. Thus, the magnetic disk can be designed with a considerably improved freedom.
