TU Wien Etched a QR Code Smaller Than Bacteria — It Can Store 2TB on One Sheet of Paper

vienna scientists just made your entire hard drive fit on a sticky note. well, a really fancy ceramic sticky note that lasts 5,000 years.

49-nanometer pixels. 1.98 square micrometers. 2 terabytes per A4 sheet. Zero power consumption. Certified Guinness World Record.

Researchers at TU Wien (Vienna University of Technology) and data storage company Cerabyte just ion-beam-etched the world’s smallest QR code into ceramic — 37% smaller than the previous record — and it can only be read with an electron microscope. The Babylonians stored data on clay tablets. These scientists basically said “hold my beer” and shrunk that concept down to the nanoscale.

Cool. Your hard drive is a ticking time bomb and the Babylonians had better long-term storage than you. Now What the Hell Do We Do? (⊙_⊙)

the babylonians carved their receipts into clay and we can still read them 5,000 years later. we put ours on SSDs that die if you look at them wrong. maybe the real technological advancement was the ceramics we made along the way.
