摘要： PROBLEM TO BE SOLVED: To provide a magnetic disk combining high density recording with reliability and to provide a magnetic disk unit provided with the same.
SOLUTION: Texture processing for imparting magnetic orientation in the circumferential direction onto a substrate 50 is applied to the magnetic disk, so that the magnetic disk has magnetic anisotropy in the circumferential direction. A base film, a magnetic recording film 60, a protective film 62 and a lubricant film 64 are layered on the surface of the substrate. The surface of the magnetic disk is so formed that a contact ratio value [BH1.0 nm] at a height of 1.0 nm or above is 7 to 15% when the height at which the contact ratio is 50% is adopted as a reference in a surface roughness versus loading curve.
