PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording medium which has sufficient durability, moisture resistance and stain resistance, and has a suitable lubricating layer holding R/W characteristics. SOLUTION: In a method for manufacturing the perpendicular magnetic recording medium 100 having a magnetic recording layer 122, a medium protective layer 126 and a lubricating layer 128 in this order on a substrate 110, the method for manufacturing the perpendicular magnetic recording medium is characterized in that it comprises: a step to measure the CF bond density of a lubricant; and a step to film form the lubricating layer with the lubricant when the measured CF bond density is in a range of 2.0×10<SP>22</SP>to 2.7×10<SP>22</SP>atoms/cm<SP>3</SP>.
