A sufficiently short defect will be reliably covered by the error-correcting codes in the system. For CD, you're nominally fine losing up to 2.5mm. I haven't looked into DVD/BD, but they're probably better.
I would think they would be worse actually, since they have much more data packed in and therefore have much smaller pits and lands.
DVD's are especially prone to skipping, and I'm sure this is why. Never had a problem with bluray's but that's most likely due to them being manufactured much more solidly, and with scratch resistant coating.
