Abstract
A system according to one embodiment 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 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. Additional systems and methods are also presented.
