ABSTRACT:
A magnetic recording medium includes a textured surface which is textured in a predetermined direction, a Cr-based underlayer provided on the textured surface and having Cr<110> preferred growth along the predetermined direction so that over approximately 50% of Cr<110> are oriented along the predetermined direction, and a Co-based magnetic layer provided on the underlayer and having Co(1120) preferred growth along the predetermined direction.
