| Research Abstract |
This research was pursued to realize servo signal recording by using magnetic printing technology onto next generation hard disks with recording density over 1 Tbit/inch^2 with high accuracy, high speed and low cost, showing that the realization is possible. CoPt patterned master media with perpendicular magnetic anisotropy and high magnetization made the printing performance considerably improve. Moreover, it was clarified that the printing performance was still more improved by using CoPt/Ta/FeCoB/Substrate stacked structure master media.
