ABSTRACT:
A magnetic recording medium includes a substrate, an AlFe-based alloy layer provided above the substrate, an underlayer provided on the AlFe-based alloy layer, and a recording layer provided on the underlayer and magnetized in a predetermined recording direction when being recorded with information. The substrate has a textured surface having grooves formed approximately along the recording direction.
