| 摘要 |
A high areal recording density, anti-ferromagnetically coupled ("AFC") perpendicular magnetic recording medium comprises:a layer stack formed over the surface of a non-magnetic substrate (2), comprising, in overlying sequence:an underlayer (3) comprised of a magnetically soft ferromagnetic material;at least one non-magnetic interlayer (4);a perpendicularly anisotropic stabilization layer (6) comprised of a hard ferromagnetic material;a non-magnetic spacer layer (7); anda perpendicularly anisotropic main recording layer (5) comprised of a hard ferromagnetic material;wherein the perpendicularly anisotropic stabilization layer (6) and the perpendicularly anisotropic main recording layer (5) are anti-ferromagnetically coupled (AFC) across the non-magnetic spacer layer (7) to orient the magnetic moments thereof anti-parallel and thereby provide the medium with increased |
