摘要：
The feasibility of perpendicular magnetic printing for ultrahigh-density hard disks (HDs) was investigated by using the micromagnetic simulation. Our results suggest that the exchange constant dependence of the printing performance has a maximum value and the applied printing field should be less than the coercivity. Although the printing performance slightly deteriorates as the recording density increases, the printing performance is expected to be kept 70% at 1 Tb/in(2). Therefore, it was clarified that the perpendicular magnetic printing is feasible even at ultrahigh density such as 1 Tb/in(2).
