STAMPER FOR TRANSFERRING PATTERN, METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM BY USING THE STAMPER, AND THE MAGNETIC RECORDING MEDIUM

摘要

A pattern transfer stamper 1 according to the present invention transfers an uneven pattern to a deformable surface of a member which is a base for manufacturing a magnetic disc D including a data region 81 and a servo region 82 positioned adjacent to the data region 81 in the circumferential direction. The pattern transfer stamper 1 includes at least a guard band pattern portion 11 corresponding to the data region 81. The guard band pattern portion 11 includes linear projections 11a extending in the circumferential direction and spaced from each other in the radial direction. A support projection 15 for supporting ends 11b of the linear projections 11a is provided to be integrally connected to the ends.
