Engraving data on a titanium record would be a way to store it for many years even with exceptionally poor environmental conditions (fire, flood, locusts, plagues, what have you).

M-DISC [0] will probably cover most of the scenarios. It's still expensive, though.

Yes. And it doesn’t have to be titanium per se. Cerabyte is trying to use ceramic. Even rocks might be good enough.

Nasa preferred gold (more specifically copper plated with nickel and then plated with gold) https://en.wikipedia.org/wiki/Voyager_Golden_Record

		To be fair, that's not simply an archival disc, but also something explicitly intended to be readable by intelligent life elsewhere in space. The encoding of data was optimized for simplicity above all else.
