I was able to repair couple of unreadable CD by copying them to CD-R. It took long time (couple of hours for one CD) but got recovered working copies.The opposite with me with original retail ones, the more they were burnt the worse the sound got. Proved it many times when hearing a loved CD at a friends, borrowing, it to burn <4x, then later getting the retail one used same version and it sounds better But burnt ones that wouldn’t even read TOC were readable using another brand blanks. The more they were burnt the worse the got, then there’s the burnt ones that are unplayable unless certain blanks were used, but perfectly fine with every retail cd. |
The first retail stamped cd will have some error correcting, this substitutes the unreadable pit for what came before it be it 0 or 1, so it has a 50% of getting it right. Every copied cd has the same each way bet with that original error, and then it has it’s own now to contend with also that the original didn’t, and so on and so on. The more you copy the original the more the errors grow and each one only has 50% of getting it right. Pick up an original German first release of Propagander "A Secret Wish" it has the on the back from Sony the stamping errors with corrections that happen and at what seconds in each track.

Sorry no they don’t, there far more error correction going on with burnt CD’s The picture below is is of the 1’s and 0’ pits using a micron camera, and shows the Retail Stamped Aluminum CD vs Gold layer burnt CD vs Aluminum burnt CD. https://ibb.co/vYN4Dnc As you can see the stamped is far better to read for lasers with minimal errors.
