An object of the present invention is to provide a method of manufacturing a perpendicular magnetic recording medium (100) in which both of a coercive force Hc and reliability can be achieved at a higher level even with heating at the time of forming a medium protective layer (126) and to provide the perpendicular magnetic recording medium (100). Thus, in a typical structure of the present invention, in the method of manufacturing the perpendicular magnetic recording medium (100) including at least a magnetic recording layer (122b), which is a ferromagnetic layer of a granular structure in which a non-magnetic grain boundary part is formed between crystal grains each grown in a columnar shape, and a medium protective layer (126) with carbon hydride as a main component in this order on a disk base (110), the method includes a magnetic recording layer forming step of forming the magnetic recording layer (122b) so that the grain boundary part contains oxides of a plurality of types and a medium protective layer forming step of forming the medium protective layer (126) in a state where the disk base (110) having the magnetic recording layer (122b) formed thereon is heated at 160 to 200 degrees Celsius. |
