A method for manufacturing a magnetic recording medium is provided which can sufficiently reduce variations in surface roughness even in the simultaneous presence of a region of a relatively wide concave and convex portion and a region of a relatively narrow concave and convex portion in the recording layer. The method includes the steps of etching a recording layer based on a (first) mask layer to process it in a concavo-convex pattern, and depositing a filler over the recording layer and the mask layer to fill a concave portion with the filler. In between those steps, provided is the step of removing part of the first mask layer over a recording element (a convex portion of the recording layer) by dry etching in which an etching rate for the mask layer is higher than that for the recording layer so that the mask layer remains over the recording element.
