A method of making an embossing drum for embossing tape media, the method comprising:
- assembling together multiple stamper plates into a stamper plate body, the multiple stamper plates including a first stamper plate and a second stamper plate, the assembling comprising coupling a first stamper plate having first land and groove patterns to a second stamper plate having second land and groove patterns that are an inverse of the first land and groove patterns, each of the first stamper plate and the second stamper plate having 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.
An embossing drum for embossing tape media, the embossing drum comprising:
- a first stamper plate having first land and groove patterns for embossing the tape media;
- and
- a second stamper plate having second land and groove patterns that are an inverse of the first land and groove patterns positioned proximate the first stamper plate for embossing the tape media, wherein each of the first stamper plate and the second stamper plate 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.
