摘要：
An imprint stamper for manufacturing a recording medium includes a first transfer region which corresponds to a servo region of a recording medium using a sector servo system and has a pattern with a plurality of quadrilateral recess or protrusion portions formed in a surface thereof, and a second transfer region which corresponds to a data region of the recording medium and has a pattern with a plurality of dots of recess or protrusion portions arrayed in a form of a hexagonal lattice in a surface thereof.
