Re: [DIYbio] Longterm genomic Data storage

then laser etch the QR code onto a piece of clear cubic zirconium with that fancy focal point etching thing they do at shopping malls to immortalize some mundane family photo or moment...and frame it in a platinum-iridium alloy so thermal expansion is damn near zero. should last a few millennia at least, no? :P

So, you pack the sheet with QR codes at mimimum size assuming the high DPI coverage.

The image would have to have overlap zones at paper fold lines, or no folds and a margin,
and in the second case, no overlap repeated zones would be needed.

But what if insects we have in north America called silverfish got in the box?
They eat paper!  Even in absence of much humidity.

If stored in a pharaoh's tomb, with a wax seal on the wooden case, they might go 4000 years...
