Abstract
An energy assisted magnetic recording (EAMR) system includes a magnetic recording medium including a plurality of bi-layers and a magnetic recording layer on the plurality of bi-layers, a magnetic transducer configured to write information to the magnetic recording medium, and a light source positioned proximate the magnetic transducer and configured to heat the magnetic recording medium. Each of the plurality of bi-layers includes a heatsink layer and an amorphous under-layer on the heatsink layer.
