PROBLEM TO BE SOLVED: To provide a magnetic recording medium in which the thermal changes in the backing layer characteristics is improved, in the magnetic recording medium used in a magnetic recording device to conduct signal writing at temperature higher than that at which signal is held. SOLUTION: In the magnetic recording medium used in the magnetic recording device for conducting signal writing at the temperature higher than that at which the signal is held, the magnetic recording medium is constituted, by sequentially laminating at least a soft magnetic backing layer, a heat conduction preventing layer, an underlayer, a magnetic recording layer, and a protective layer on a non-magnetic substrate.
