Title: The Rosetta Disk and Strategies for Very Long-term Archiving
Location: 67-3111 Chemla Room

The Rosetta Disk, developed at The Long Now Foundation, is a microscopic archive designed to last for thousands of years. The 7 cm diameter disk is made of nickel, created by electroplating a silicon master etched with a FIB. Each page is .48 mm across, enabling the disk to be “read” (like a book) at 1000x magnification.

Inspired by the Rosetta Stone artifact that enabled the decipherment of Egyptian Hieroglyphs, the disk contains over 13,000 pages of documentation on over 1,500 human languages. As the first entry into the Long Now library, the disk is intended to provide a key to decipherment for any information we leave to the future in human language form.

In this talk, I’ll describe the creation of the Rosetta Disk, including an early prototype on the Rosetta ESA mission to comet 67P. While doing so, I’ll discuss strategies to consider when developing and deploying any technology for long-term archiving.
