ABSTRACT:
A magnetic recording medium for use in a thermally assisted recording system is disclosed. The magnetic recording medium comprises at least a magnetic layer, a protective layer and a lubricant layer formed on a nonmagnetic substrate, wherein a lubricant of the lubricant layer exhibits such a heat resistance that an amount of volatilization when the magnetic layer is heated to a temperature not lower than a temperature Tw is less than 1% with respect to an initial amount of the lubricant in an unheated condition. The present invention addresses a problem of the heat resistance performance of the lubricant for use in magnetic recording media and provides a magnetic recording medium exhibiting high heat resistance.
