Abstract
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.
Claims11
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 from one another, the separating portion comprising a low thermal conductor having a thermal conductivity lower than that of the magnetic recording bit regions.
