Abstract

Storing large amounts of information over even relatively short time scales of 100 years, comparable to the human memory span, is a challenging problem. The major challenge is the lack of appropriate storage technology and a medium possessing the advantages of both high capacity and long lifetime. We demonstrate recording and retrieval of the digital document with a nearly unlimited lifetime. The recording process of multiplexed digital data was implemented by femtosecond laser nanostructuring of fused quartz.
