PROBLEM TO BE SOLVED: To provide a manufacturing method of a perpendicular magnetic recording medium by which magnetic separation between magnetic particles is satisfactorily performed, and the perpendicular magnetic recording medium is easily manufactured.;SOLUTION: A granular film 15 including the magnetic particles 15a and MoCuO 15b enclosing the magnetic particles 15a is formed on a substrate 11. The MoCuO 15b is removed by wet etching the granular film 15 by using an alkali solution or water to form gaps. The film from which the MoCuO 15b is thus removed is used as a magnetic recording layer.;COPYRIGHT: (C)2010,JPO&INPIT
