World's smallest QR code, smaller than bacteria, could store data for centuries
www.sciencedaily.com

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.

    This is just a ploy to get me to buy a new phone with a better camera isn’t it?

    Could microfiche make a comeback with this?

      Optar would be a much better choice than QR codes if you want to store lots of data on microfiche. It stores about 200 kB per page.

        I remember seeing that years ago, wanted to make like a photoresist mask to etch it into metal.

        These days you could probably feed it to a laser engraver, get some nice depth on a thicker sheet of e.g. aluminium, would be a nice display piece at least.

    The smaller the more easily damaged, right? The uffington horse approach will last longer than the website it points to.
