Abstract:
A method is provided for making stamper plates for an embossing drum for embossing tape media. At least one first stamper plate is formed using a master template. The at least one first stamper plate includes first land and groove patterns that are an inverse of the master template land and groove patterns. At least one second stamper plate is formed from the at least one first stamper plate. The at least one second stamper plate includes second land and groove patterns that are an inverse of the first land and groove patterns. Furthermore, the first stamper plates and the second stamper plates have four sections arranged in a travel direction of the tape media, a first and a fourth of the four sections having land and groove patterns that are laterally mirrored with respect to each other. A first stamper plate is coupled to a second stamper plate to form part of the drum for embossing tape media.
