??A multi-layered master medium with perpendicular anisotropy is proposed. The multi-layered master medium is composed of a thin CoPt film with perpendicular magnetic anisotropy, a nonmagnetic interlayer with several nanometers in thickness, and a soft magnetic FeCo-based film. Magnetic printing characteristics by using single-layered and multi-layered master media were investigated through experiments. The best magnetic printing characteristics were obtained by using the multi-layered master medium. This is because the multi-layered master medium has larger recording field than the single-layered master media near side wall of convex part due to high perpendicular anisotropy of the CoPt film and image effect by the soft magnetic film.
