JOINT DESIGN OF THERMALLY-ASSISTED MAGNETIC RECORDING HEAD AND PATTERNED MEDIA FOR HIGH OPTICAL EFFICIENCY

摘要

PROBLEM TO BE SOLVED: To provide joint design of a thermally-assisted magnetic recording head and patterned media for high optical efficiency. SOLUTION: A system includes a magnetic recording medium having a magnetic layer with features in a discrete track configuration or a bit patterned configuration and an underlayer adjacent to the magnetic layer, the underlayer comprising a material capable of forming surface plasmon resonance; and a magnetic head having: a writer for writing to the medium; and a near-field transducer for heating the medium for thermally assisted recording.
