"The Rosetta Disk is the physical companion of the Rosetta Digital Language Archive, and a prototype of one facet of The Long Now Foundation’s 10,000-Year Library. The Rosetta Disk is intended to be a durable archive of human languages, as well as an aesthetic object that suggests a journey of the imagination across culture and history." (https://rosettaproject.org/disk/concept/ https://rosettaproject.org/disk/concept/) "For the production of nano inscribed nickel wafers or plates, the archival data in the form of pdf format is first submitted and organized sequentially or indexed systematically. After file conversion and other preparation for NanoRosetta processing, the documents or other data are then recorded onto a glass wafer by modulating a laser beam in a spiral or concentric manner using a polar raster direct laser etch. A matrix process in electroforming creates “father” nickel master from the inscribed glass wafer. An intermediate “mother” and final ”son” can then be generated from this nickel “father” master wafer. For mass production, polymer copies can also be provided in lieu of nickel “sons.” We also have the ability to combine digital data (CD or DVD) and analog human readable formats on the same disc."
