Wait, have M-Discs been discredited?
Kind of out of the loop on that. The general idea of engraving stuff with a laser in something like glass or diamond seems legit though.
M-Discs are DVDs and Blurays with a less volatile chemical composition, like rock. It takes a stronger laser to etch them, so an M-Disc-capable burner is required, but they claim to last one thousand years (in favorable conditions like a dry cave)
It sounds like somewhat different tech then.
Sure, but you were talking about media that last as long as paper, so I thought it deserved a mention.
yeah fair
