Magnetic recording medium comprising an aluminum substrate in which pores formed by anodic oxidation contain crystallographicaly discontinuous particles of Fe-alloy

摘要

Provided according to the present invention are a perpendicular magnetic recording medium filled with a magnetic metal containing Fe as a main component in the fine pores of an alumite formed by anodic oxidation of a surface of an Al or Al alloy substrate, the particles of Fe in the filled magnetic metal being crystallographically discontinuous, and a process for the production thereof.
