Patent ID: 7247343

Claim:
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/V 0 ≦−0.003×( L·d/t )+1.2 where V 0 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.
