[Problem] The concentration distribution in a perpendicular direction of ions implanted in a magnetic recording layer of a perpendicular magnetic recording medium is made a suitable one corresponding to a layer implanted with ions. [Solution] A method of manufacturing a perpendicular magnetic recording medium 100 includes a magnetic recording layer forming step of forming a magnetic recording layer 122 on a disk base 110, a resist layer forming step of forming a resist layer 130 on the magnetic recording layer, a patterning step of processing the resist layer so as to vary the thickness of the resist layer partially, thereby forming a predetermined pattern having a recessed part and a projected part and an ion implanting step of implanting ions into a plurality of layers including the magnetic recording layer with the resist layer interposed, where, at the ion implanting step, a layer to be implanted with ions is determined by adjusting an energy amount to implant ions, and a total amount of ions to be implanted into respective layers is determined by adjusting a time period for which the energy amount is held.
