Beschreibung
Zusammenfassung:	A magnetic data storage medium comprising: an ion doped magnetic recording layer having a continuous grading of coercivity or anisotropy, wherein the coercivity or anisotropy is at a minimum substantially at one side of the magnetic recording layer, and having substantial portion of maximum coercivity or anisotropy at the other side of the magnetic recording layer. Also, a method of fabricating a magnetic data storage medium is included.
