Method for manufacturing a magnetic recording medium

摘要

A method for manufacturing a magnetic recording medium is provided, which can efficiently manufacture a magnetic recording medium that includes a recording layer formed in a concavo-convex pattern and has good recording and reproduction characteristics. The method includes: a non-magnetic material filling step of depositing a non-magnetic material over a recording layer formed in a predetermined concavo-convex pattern over a substrate so as to fill a concave portion of the concavo-convex pattern with the non-magnetic material; and a flattening step of removing the excess part of the non-magnetic material above the recording layer by dry etching so as to flatten the surfaces of the non-magnetic material and the recording layer. The flattening step includes a former flattening step and a latter flattening step for finishing.
