ABSTRACT:
A thermally assisted magnetic recording medium includes a substrate having a first surface and a second surface opposite to the first surface. A recording layer is formed on the first surface of the substrate. A plurality of thermally conductive regions are provided at the first surface of the substrate to extend in parallel to each other and about the center of rotation of the recording medium. The thermally conductive regions have a higher thermal conductivity than the substrate, and are at least partially embedded in the substrate.
