Not all is lost: Try to find another computer with
another CD drive.
Various drives handle these kinds of broken CDs differently. You could
also do an analogue copy, which can be of almost the same quality as a
digital rip.
Do these things deliberately have broken CIRC (L1 errors)? They must sound
distorted, as when audio data doesn't survive level 2 - that's it. Unlike
CD-ROM Mode 1 Form 1 (data) which has L-ECC (and retries), you're in the
land of data loss and frame interpolation.
Other than that I can only think of searching some P2P
networks for
the contents of your CD, which you are kept away from although you
paid for it.
Those would be lossily compressed. You'd be better off making an analogue dub.
