Billion Year Storage Media

Thorfinn.au writes "Even though the data density of digital information storage has increased tremendously over the last few decades, the data longevity is limited to only a few decades. If we want to preserve anything about the human race which can outlast the human race itself, we require a data storage medium designed to last for 1 million to 1 billion years. In this paper a medium is investigated consisting of tungsten encapsulated by silicon nitride which, according to elevated temperature tests, will last for well over the suggested time."
