A method for producing a magnetic recording medium, includes: forming an SOG film on a surface of a magnetic layer; forming a concavo-convex structure in the SOG film comprising one selected from a group consisting of silica glass, alkylsiloxane polymer, methyl silsesquioxane polymer, hydrogen silsesquioxane polymer and hydro alkylsiloxane polymer; etching the SOG film to expose the surface of the magnetic layer; etching the exposed surface of the magnetic layer by ion milling; and forming a filling layer on the surface of the magnetic layer while leaving a portion of the magnetic layer having been subjected to the ion milling.
