摘要

PROBLEM TO BE SOLVED: To provide a system, method and apparatus for perpendicular magnetic recording media having decoupled control and graded anisotropy.;SOLUTION: A structure for high-performance perpendicular magnetic recording media has: a substrate with a plurality of sequential layers including an adhesion layer, a first soft magnetic underlayer (SUL), a coupling layer, a second SUL, a seed layer, a Ru layer, and an onset layer; at least one oxide layer which is on the onset layer and has a composition with graded anisotropy to improve overwrite performance of the media; an exchange coupling layer (ECL) on the at least one oxide layer; a cap layer; a decoupling-controlled layer between the ECL and the cap layer to reduce lateral exchange coupling in the cap layer on the ECL; and a carbon overcoat on the cap layer.;COPYRIGHT: (C)2012,JPO&INPIT
