US Patent:

20160001511, Jan 7, 2016

Filed:

Sep 11, 2015

Appl. No.:

14/851110

Inventors:

- Redwood City CA, US
Joseph J. Kozak - Belchertown MA, US

International Classification:

B29D 11/00

Abstract:

Various embodiments herein include utilities for generating embosser drums that are used to pre-format optical media such as optical tape with a pattern of nanostructures such as wobbled grooves. One utility includes generating a plurality of replicas from an embossing master, bonding the replicas together to form a bonded replica structure having a surface with the nanostructure pattern imprinted therein, creating a replica of the bonded replica structure and electroforming a metallic layer onto the bonded replica structure replica to create a single, one piece, metallic shim which can be used to create a weld-less embosser drum.
