Researchers etched a 1.98-square-micrometer QR code into a thin ceramic film, readable only with an electron microscope, demonstrating a durable, energy-free data storage method that could hold over 2 TB per A4 sheet for centuries or millennia and has earned a Guinness World Record.
Storing data for decades or centuries requires finding a storage format that can be trusted to last. Digital storage media like hard drives and SSDs can degrade over time and eventually fail, while file format obsolescence can make data unreadable. Archival-grade optical discs like M-DISC promise to last hundreds or even thousands of years, while magnetic tape can last for up to 50 years or more. Cloud storage is not an option for truly long-term storage.
