PROBLEM TO BE SOLVED: To provide a magnetic recording medium capable of enhancing writing performance for a long time even when regularity of a regular alloy used for a recording layer is changed while the magnetic recording medium is efficiently heated with a small amount of energy consumption. SOLUTION: The magnetic recording medium has such a structure that a soft magnetic layer 141 is formed on a rigid substrate 10, a soft magnetic layer 143 is formed thereon via a non-magnetic intermediate layer 142 and then an intermediate layer 16 composed of an oxide, a crystal orientation controlling and low thermal conduction intermediate layer 18, a granular recording layer 20 including essentially an Fe-Pt alloy composed of a composition expected to take an L1<SB>0</SB>structure at a stage where regulation is advanced, a cap layer 22 composed of an Fe-Pt alloy or a Co-Cr-Pt-B alloy, a protective layer 24 and a lubricant layer 26 are formed thereon.
