Abstract:
1. A method of manufacturing a magnetic recording medium, comprising the steps of: forming a magnetic layer on at least one surface of a nonmagnetic substrate; forming a groove in which a nonmagnetic section is formed by etching a portion corresponding to a formation region of the nonmagnetic section in the magnetic layer and a magnetic recording section formed of the magnetic layer; applying a resin having an active energy ray curable functional group to the surface of the magnetic recording section so as to fill the groove; pressing a plate material against the resin so that the smooth surface of the plate material is in contact with the surface of the resin to make the surface of the resin smooth; removing the plate material from the resin after the step of pressing the plate material; and forming the nonmagnetic section in the groove by etching and removing a portion located above the surface of the magnetic recording section in the resin having a smooth surface after the step of removing the plate material.
