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.

It appears that these pictures show physical burn to gold or aluminum layer. CD-Rs have photosensitive dye - there is no physical burning. CD-Rs can be written at speeds up to 52x. Reading at 1x should be fine, otherwise we would have huge problem with data CD-Rs. Even if lands are not perfect and produce some jitter it goes thru the buffer. It is possible to output data at exact time intervals, since data stream rate is based on the same crystal clock. |
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.

Error in CD reading can be corrected by going multiple times over the same sector. CDP cannot do that working in real time (reading only once). That way CD-R copy can be better than original CD. 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. |
