ABSTRACT:
To provide a magnetic recording medium with good record and reproduction characteristics. In the magnetic recording medium having an anodic oxidized alumina nanohole film filled with a magnetic substance, the anodic oxidized alumina nanohole film13is formed on a substrate16with at least one base electrode layer15sandwiched therebetween, the base electrode layer15is a film that has fcc structure and whose (111) face is oriented in the direction perpendicularly to a substrate, and the fillers14in the alumina nanoholes10have hcp structure and include hard magnetic substance whose principal component is Co and whose c-axis is perpendicular to the substrate.
