There's an orthogonal problem: does your DVD drive read CDs? I mean, sure it does, on the abstract level of compatibility; but the _material_ of the physical data carriers degrades. Audio CDs from the 1990s are still listenable (as there's far more error correction going on in the ear of the beholder), but data CDs? Not good, and getting worse. And that's not to mention magnetic tapes, where the charge fades even faster...

BaFe tapes don't seem to have issues with "data fading". And BD-R uses phase-change recording, which is very, very stable and not affected by fungi or other ways the dye tends to rot/degrade in CD-R/DVD-R. Modern, high-coercitivity magnetic data tape only really has issues with hydrolysis of the binder that holds the magnetic particles to the PET film. This is prevented by very, very dry storage under about 15 degree Celsius.
