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