First example I thought of is the titanium punch sheets and wordlists for crypto wallet recovery phrases https://shop.ledger.com/products/cryptotag-zeus and https://github.com/bitcoin/bips/blob/master/bip-0039/bip-003...

There is also Microsoft Project Silica which I recall seeing in person at their EBC playing back a movie from it https://www.microsoft.com/en-us/research/project/project-sil...

Then there is m-disc which uses the DVD+R and BD-R/BDXL standards but writing to a sort of glass rather than to the traditional medium. These are cool as they play back n regular players too. https://www.mdisc.com/
