Magnetic recording medium with CR <110> preferred growth along a predetermined direction, method of producing the same and magnetic storage apparatus

摘要

A magnetic recording medium including a textured surface that is textured in a predetermined direction. The textured surface preferably has a distance lambda between two mutually adjacent texturing lines satisfying a relationship 5<lambda<30 nm, and an angle phi between the textured surface and an oblique texture plane satisfying a relationship 0.5<phi<7 degrees. There is also a Cr-based underlayer provided on the textured surface that has a preferred growth so that a number of grains having Cr<110> in a vicinity of 0 degrees or 90 degrees with respect to the predetermined direction is two times or greater than a number of grains having Cr<110> in a vicinity of 45 degrees with respect to the predetermined direction. Additionally, there is also a Co-based magnetic layer provided on the underlayer that has Co(1120) preferred growth along the predetermined direction.
