摘要:
A method for producing a magnetic recording medium comprising at least a recording layer and a protective film provided on top of a non-magnetic substrate, the method comprising, in the following order, forming a continuous recording layer on the substrate, forming a patterned resist layer, partially removing the recording layer based on a resist pattern, applying an organosilicon compound having an active energy beam-curable functional group onto the recording layer and regions from which the recording layer has been removed, curing the organosilicon compound with an active energy beam, etching the organosilicon compound to expose a magnetic layer, and forming a protective film.
