Method for manufacturing magnetic recording medium

A method for manufacturing a magnetic recording medium having a recording layer formed into a predetermined concavo-convex pattern over a substrate in which recessed portions of the concavo-convex pattern are filled with a non-magnetic material, the method comprising:

• a non-magnetic material filling step of depositing the non-magnetic material on a surface of a member to be processed to which bias power is applied, the member to be processed having the recording layer formed into the predetermined concavo-convex pattern over the substrate, to fill the recessed portions with the non-magnetic material, while adjusting a deposition rate V, being a film thickness of the non-magnetic material deposited per unit of time, by adjusting deposition conditions including the bias power,
• wherein the non-magnetic material filling step is carried out by adjusting the deposition conditions in such a manner as to satisfy the following relationship
• 0.1≦V/V0≦−0.003×(L·d/t)+1.2
• where V0 represents the deposition rate in a case that the bias power is 0, t represents a film thickness of the non-magnetic material, L represents a width of a projected portion of the concavo-convex pattern, and d represents a depth of the recessed portion of the concavo-convex pattern.
