Abstract
Granular-type FePt films with perpendicular magnetic anisotropy are obtained on top of Fe-Ta-C magnetic soft underlayer by annealing FePt/MgO multilayers. For high-density perpendicular magnetic recording medium application, the issues regarding the FePt film crystallographic texture, microstructure, chemical ordering and magnetic properties are addressed in this paper. Based on this medium design, double-layered FePt disks are fabricated on 2.5-inch glass discs. The magnetic recordin performances of these disks are evaluated by a spin-stand. The results reveal a close correlation between the disks SNmR recording performance with the initial multilayer structure.
