Patent ID: 7296514

Claim:
A convex/concave pattern-forming stamp having on a surface thereof a predetermined annular area formed with convex/concave pattern-forming protrusions for forming a convex/concave pattern in a resin layer on a surface of a substrate by being pressed against the resin layer, wherein: the annular area is defined to have approximately the same size as a track-forming area of a magnetic recording medium; pressure-dispersing protrusions for dispersing pressure applied to the resin layer when the convex/concave pattern-forming protrusions are pressed against the resin layer are formed in at least one of an outer area located radially outward of the annular area and an inner area located radially inward of the annular area; and the pressure-dispersing protrusions are formed such that a width of each of the pressure-dispersing protrusions increases towards an outer periphery of the stamp.
