Recording performance of granular-type FePt-MgO perpendicular media

Abstract

Double-layered perpendicular magnetic recording media, composed of granular-type FePt-MgO films on Fe-Ta-C soft magnetic underlayer, are fabricated on to 2.5-in glass discs with the stack structure of [MgO x-nm/FePt y-nm]/sub n//MgO 4-nm/SiO/sub 2/ 4-nm/Fe-Ta-C 200-nm/Glass disk. After annealing, granular films of FePt-MgO with high perpendicular magnetic… (More)
