Magnetisches Speichermedium mit senkrechter Anisotropie. |
摘要 |
A perpendicular magnetic storage medium comprising a substrate and a perpendicular magnetic anisotropic film formed on the substrate, characterized in that the perpendicular magnetic anisotropic film is a film of a sub-oxide of a metal having a composition described by a general formula [(Fe1-xCox)1-yMy]1-zOz [where 0.01</=x</=0.75, 0</=y</=0.30, 0.05</=z</=0.50 and M means at least one metal excluding Fe and Co.]; and has an easy magnetization axis being perpendicular to a plane thereof, and both a peak of diffracted X-ray intensity caused by oxidized Fe and a peak of diffracted X-ray intensity caused by metal state Fe and Co and Metal M observed in X-ray diffraction spectrum. The perpendicular magnetic storage medium of the present invention can be produced easily and economically at a low substrate temperature, and has high wear resistance, high recording/reproducing sensitivity and high recording density. |
