They may be more susceptible due to the finer grooves alone, I guess? Although so far I've also never had any DVD or Blu-ray go bad.

Recordable discs are another matter, though. Much more sensitive because the pits are "burned" instead of "pressed" (not sure about the correct terminology). And some of those materials were so bad that back in the day, I often had blank discs that went bad before I even had a chance to burn them. Nowadays I'm using M-Discs and hope they'll hold up their promise. They should outlive me, anyway.
