A magnetic recording medium includes a nonmagnetic substrate and at least a magnetic layer, a protective layer, and a lubricating layer provided on the nonmagnetic substrate. The magnetic recording medium is characterized in that the lubricating layer is formed of a lubricating agent represented by general formulas (1), (2) or (3), in which substituents R, R, R, and Rin the lubricating agent represent organic groups, at least one of the substituents Rand Rat the end part of the lubricating agent and the substituents Rand Rcontain a plurality of functional groups, and the shortest distance between the functional groups is a distance of three or more atoms, preferably five atoms. The magnetic recording medium may be used for a heat assisted recording method in which the temperature of the magnetic layer reaches 150&#xb0; C. to 200&#xb0; C. The magnetic recording medium is characterized in that the amount of the lubricating agent volatilized in the lubricating layer is less than 10% of the initial layer thickness.
