ABSTRACT:
A method for manufacturing magnetic recording media is provided, by which a magnetic recording medium that has a recording layer formed in a concavo-convex pattern, a sufficiently flat surface, and good recording/reproducing properties can be manufactured. The method includes the steps of: depositing a first filling material over a workpiece to cover recording elements formed as convex portions of the concavo-convex pattern, and to fill at least part of a concave portion; depositing a detection material over the first filling material; depositing a second filling material over the detection material; and irradiating a surface of the workpiece with a process gas to flatten the surface. In the flattening step, a component of the detection material removed from and flying off the workpiece is detected to stop the irradiation with the process gas based on a result of detecting the component of the detection material.
