Patent ID: 8153205

Claim:
A method of manufacturing a patterned medium, comprising: depositing a magnetic recording layer and then applying an ultraviolet curable resin on both surfaces of a medium substrate; pressing a first resin stamper and a second resin stamper each comprising patterns of recesses and protrusions, corresponding to recording tracks or recording bits and servo information in a patterned medium, against both surfaces of the medium substrate wherein a direction of a vector from a center position of the medium substrate toward a center position of the first resin stamper is off-oriented from a direction of a vector from the center position of the medium substrate toward a center position of the second resin stamper in order to imprint the patterns of recesses and protrusions on the ultraviolet curable resin; and irradiating the ultraviolet curable resin with an ultraviolet ray through the first and second resin stampers in order to cure the ultraviolet curable resin.
