ABSTRACT:
Patterned magnetic recording media and associated methods of fabrication are described. The patterned magnetic recording media includes a perpendicular magnetic recording layer that is patterned into a plurality of discrete magnetic islands. The patterned magnetic recording media also includes an exchange bridge structure formed from magnetic material that connects the islands of the perpendicular magnetic recording layer. Connecting the islands with magnetic material increases exchange coupling between the islands, which makes the islands more magnetically stable.
