摘要：

A simple technique for bit-patterned media was proposed to increase achievable areal recording densities beyond 2 Tbit/in(2). Introduction of longitudinal magnetic anisotropy to the media indicated reduced effect of magnetostatic interaction between the dots. Recording simulation with a shielded planar pole head exhibited increased write shift margins in both down and cross track directions compared with that of the perpendicular anisotropy media. It was suggested that recording of an areal density of 2.5 Tbit/in(2) would be realized with a down and cross track margins of 3.5 and 4.0 nm, respectively. Better recording performance at high areal densities is expected if suitable head could be designed. (C) 2008 Elsevier B.V. All rights reserved.
