Optical tape embosser drum with shim identification

A method of making stamper plates for an embossing drum for embossing tape media, the method comprising:

• forming one or more first stamper plates using a master template, the one or more first stamper plates having first land and groove patterns that are an inverse of master template land and groove patterns of the master template;
• forming one or more second stamper plates from one of the one or more first stamper plates such that the one or more second stamper plates have second land and groove patterns that are an inverse of the first land and groove patterns;
• and
• coupling the one first stamper plate to the one second stamper plate to form part of the drum for embossing tape media;
• wherein each of the one or more first stamper plates and the one or more 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.

• bending the second stamper plate and the first stamper plate such that each of the second stamper plate and the first stamper plate has a curved configuration;
• and
• coupling the first stamper plate with the second stamper plate to form a cylindrical body,
• wherein the first stamper plate and the second stamper plate each 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.
