ABSTRACT:
This invention provides a magnetic recording material having a regular orientation which comprises aluminum or aluminum alloy on the surface of which a film having a great number of micro pores is formed by an anodic oxidation, each of said pores being packed with a magnetic substance. As compared with conventional magnetic recording materials, this magnetic recording material is excellent in anisotropy, ability to effect high density recording, uniformity of unit magnetic elements in size and dimension ratio with regular orientation, and highness of leakage flux.
