PROBLEM TO BE SOLVED: To provide a magnetic recording medium which has a recording layer formed of a projecting and recessing pattern, and also has a high recording density, and a high recording reliability of a magnetic signal. SOLUTION: The magnetic recording medium 10 has a substrate and the recording layer 16 formed of the predetermined projecting and recessing pattern on the substrate, wherein the projecting part of the projecting and recessing pattern configures a recording element 14. A nucleation magnetic field Hns of a side wall portion 14A of the recording element 14, a nucleation magnetic field Hnc of a center portion 14B of the recording element 14, a coercive force Hcs of the side wall portion 14A, and a coercive force Hcc of the center portion 14B, satisfy relations of an inequality (I) Hnc<Hns and inequality (II) Hnc/Hcc<Hns/Hcs.
