Sure. But in that case (a Roman Empire-like collapse - most technology still intact - or a more total collapse with a recovery within a few decades) it’s not just that there’ll be a lot more CD-R and DV-R drives around. It’s that there will be vastly more data discs around, because it’s a common standard around the world.
How many Rosetta Disks are there? How many different Rosetta Disks - with different subject matter are there? Even if you make a few hundred copies and scatter them around the world, CD-R and DV-Rs and drives will still be far more common.
In a total back-to-the-stone-age-for-centuries collapse (this seems VERY unlikely without humanity becoming extinct altogether) - the one-in-a-million still-working CD-R and DV-R drives will likely outnumber the Rosetta Disks.
In a REALLY long-term collapse, Rosetta Disks have the advantage being microscope readable. But they’re readable only a century earlier. And the far smaller number means a lesser chance of some surviving. (Or being recognized for what they are.)
