ABSTRACT:
In production of a magnetic recording material which accumulates information in magnetic substance packed in micro pores extending in the thickness direction of an anodic oxide surface layer formed on an aluminum foil by anodic oxidation and electrolylic deposition, ferromagnetic substance such as Fe--Co--Ni alloys is used for packing and the pore diameter is adjusted to a range from 40 to 100 nm in order to obtain highly improved magnetic characteristics which enable high density magnetic recording.
