Abstract

Provided is a method for manufacturing a magnetic recording medium, wherein the magnetic recording medium can be surely planarized without grinding a recording magnetic layer. A manufacturing apparatus having a stop layer forming chamber (116), an embedding layer forming chamber (117), a first etching chamber (118) and a second etching chamber (119) is used, and the following steps are executed; a step of forming a recording magnetic layer with an uneven pattern, a step of filling a recessed section of the recording magnetic layer by forming an embedding layer composed of a nonmagnetic material in the recessed section, an etching step of removing an excess embedding layer by etching, and a step of forming a film of a nonmagnetic material as a stop layer prior to the etching step.
