ABSTRACT:
A high coercivity longitudinal recording media comprising FePt or similar thin films that are vacuum deposited by RF and DC sputtering. The as-deposited multilayered films are subjected to vacuum annealing. Due to the formation of the ordered phases of FePt or the like, which have very high crystal anisotropy, the annealed FePt films have large coercivity and fine grain size, suitable for use as ultra-high density magnetic recording media.
