DIAMOND OPTICAL DISCS COULD STORE DATA FOR MILLIONS OF YEARS

Summary from the TLDR newsletter

Chinese researchers have achieved a record-breaking diamond storage density of 1.85 terabytes per cubic centimeter. The diamonds are able to retain data for millions of years at room temperature without requiring any maintenance. The system currently requires complex lasers, imaging cameras, and other equipment, but the researchers believe they will be able to eventually fit everything inside a microwave oven-sized device. The technology will be particularly useful for governments, research facilities, and large libraries.
