PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic recording medium capable of recording and reproducing information of high density and to provide a magnetic recording and reproducing apparatus provided with the magnetic recording medium. SOLUTION: In the manufacturing method of the perpendicular magnetic recording medium having at least a backing layer, a base film and a perpendicular magnetic recording film on a non-magnetic substrate, the perpendicular magnetic recording film is formed by using a film having a granular structure containing at least Co, Pt and an oxide, and the perpendicular magnetic recording film is formed using a sputtering method on a condition that substrate temperature is set in a prescribed temperature range of 100 to 170°C.
