Abstract:
A track shield structure is disclosed that enables higher track density to be achieved in a patterned track medium without increasing adjacent track erasure and side reading. This is accomplished by placing a soft magnetic shielding structure in the space that is present between the tracks in the patterned medium. A process for manufacturing the added shielding structure is also described.
