ABSTRACT:
Aluminum or an aluminum alloy on the surface of which an anodic oxide film comprising a porous layer and a barrier layer having micropores in the porous layer has been formed by a primary anodic oxidation treatment is subjected to a secondary anodic oxidation treatment and an immersion treatment so as to enlarge the pore diameter of the micropores, to make the cross-sectional profile of the micropores circular, and to make the thickness of the barrier layer and thus, the length of the micropores uniform, and subjecting the so treated aluminum or aluminum alloy to an electrolytic deposition treatment in an electrolytic bath containing a magnetic substance so as to uniformly allow a large amount of the magnetic substance to be deposited in the enlarged, uniform micropores, thereby obtaining a magnetic recording material having improved magnetic intensity and magnetic characteristics.
