ABSTRACT:
A resist film is formed on the surface of a magnetic layer on a substrate. A die is overlaid on the surface of the magnetic layer. The die includes magnetic and non-magnetic regions alternately arranged on a flat surface around a groove. The resist film is embossed so that the flat surface drives the resist film into the groove of the die. The resist film within the groove gets solidified while the die is kept in contact with the magnetic layer. A magnetic field is applied to the die in contact with the magnetic layer. A magnetic field leaked out of the magnetic regions acts on the magnetic layer. Magnetic information is thus written into the magnetic layer based on the leaked magnetic field. A recording track can be established in the magnetic layer based on the solidified resist film.
