PROBLEM TO BE SOLVED: To magnetize the perpendicular magnetic layers of the projected and recessed parts of a magnetic disk medium equipped with the perpendicular magnetic layers having patterned recessed and projected surfaces, in reverse directions to each other. SOLUTION: The perpendicular magnetic layer 3 of a magnetic disk medium 1 equipped with the perpendicular magnetic layer 3 having recessed and projected surfaces is uniformly magnetized in a predetermined direction initially. Then, a magnetic field Hdu is applied in a reverse direction to the initial magnetization in a state in which the flat and smooth surface of a selective magnetizing medium 100 equipped with a magnetic layer 12 having a flat and smooth surface is in close contact with the upper surface of the projected part 5 of the magnetic disk medium 1, Thus, only the magnetization of the projected part 5 of the magnetic disk medium 1 is reversed.
