摘要： To provide a method for manufacturing a perpendicular magnetic recording medium, which is capable of coping with the much higher recording density.Disclosed is a method for manufacturing a perpendicular magnetic recording medium to be used for recording information by a perpendicular magnetic recording system, including at least a soft magnetic layer, an intermediate layer, and a magnetic recording layer on a substrate, characterized in that the method includes the step of:composing the intermediate layer of consecutive N layers (provided that N is an integer of at least 3 or more), depositing a first layer containing ruthenium (Ru) as a main component, first; setting a gas pressure during the deposition to the pressure which is higher than or the same as that in the first layer; depositing a second layer containing ruthenium (Ru), or ruthenium (Ru) containing oxygen or an oxide as a main component; and adjusting so that the oxygen content remains constant, or increases toward the uppermost layer in the second layer and succeeding layers.
