Original disk fabrication method, magnetic recording medium manufacturing method and magnetic recording medium










Image Number 4 for United States Patent #7817377.

It is made possible to fabricate a bit-patterned magnetic recording medium having a high recording density and making favorable address deciphering possible. An original disk fabrication method for irradiating a photosensitive resin film with an electron beam to draw a pattern, the method includes: irradiating the electron beam by using a plurality of blanking signals every rotation of a stage per bit unit, when drawing the pattern in a part corresponding to an address part on a photosensitive resin film.
