Abstract
Official abstract text for this publication.
A magnetic recording medium in which information can be recorded using a heat-assisted magnetic recording method comprises a recording layer formed on a substrate. The recording layer has a plurality of magnetic recording bit regions and a plurality of high thermal conductors each extending inside a corresponding one of the bit regions. The high thermal conductors have a thermal conductivity higher than that of the recording layer and assist in dissipating heat energy imparted to the bit regions during the recording of information.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnetic recording medium having a recording layer formed on a substrate, the recording layer comprising a plurality of magnetic recording bit regions, a plurality of high thermal conductors each surrounded by a corresponding one of the magnetic recording bit regions, the high thermal conductors having a thermal conductivity higher than that of the magnetic recording bit regions, and a separating portion that separates the magnetic recording bit regions fro…
