摘要： A method of manufacturing a patterned magnetic recording medium includes coating a magnetic film with a resist which is decomposed by exposure to electromagnetic radiation or an electron beam to have a low molecular weight, forming a pattern on the resist by an imprinting method, transferring the pattern to the magnetic film by using the resist having the pattern formed thereon as a mask, and removing the resist by exposing the resist to the electromagnetic radiation or the electron beam.
