I've wondered about this question: If I copy a CD/DVD on my PC, does it burn digital to digital, or does the reader convert it to analog, then the writer converts it to digital?
If that's the case, then burning a copied CD will introduce more errors, etc...
If this is the case, is there a system that goes directly from reading the digital format and then right at the output of the op-amp that reads the CD go into a digital writing buffer to write the 0s and 1s?
Thanks
