Abstract :
Recent works on perpendicular recording media were reviewed, Co-Cr alloy films are still under improvment and show a recording ability of 20 Gbit/in2 and beyond. New perpendicular recording media that have high perpendicular anisotropy have been developed. These would be candidate media for ultrahigh density recording beyond 100 Gbit/in2.
