Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.
2 terabytes of data could fit within the area of a single A4 sheet of paper
Unless it can be paper thin this does not look better than magnetic tape.
Moreover, would the handling of the material be safe from handling? I reckon you could scratch it pretty easily.
Of course this is just a theoretical exercise. Technically, there’s nothing in a QR code’s algorithm or the mathematics that prevents it from scaling infinitely. The error correction algorithm even allows up to 30% of the code to be damaged and still retrieve the data.
Practically though… Well, given it 's smaller than bacteria, paper looks more like a forrest(of plant fibers) at that scale. Paper just doesn’t support that kind of resolution.
