<p>PERPENDICULAR MAGNETIC RECORDING MEDIUM AND MAGNETIC STORAGE APPARATUS A perpendicular magnetic recording medium is provided with a substrate, a soft magnetic back layer provided on a surface of the substrate, an orientation controlling underlayer provided on the soft magnetic back layer, and a recording layer provided above the orientation controlling underlayer and having axes of easy magnetization approximately perpendicular to the surface of the substrate. The recording layer is made of a ferromagnetic material having an hcp crystal structure. The orientation controlling underlayer is made of a nonmagnetic material having an fcc crystalstructure and having NiCr or NiCu as a main component.</p> |
