Method of fabricating graded media

A magnetic data storage medium includes an ion doped magnetic recording layer having a continuous grading of coercivity or anisotropy. The medium also includes an ion-doped overcoat having an ion density that is at a maximum substantially at the interface with the recording layer and has a continuou...
