I saw something online where a scanned high-resolution image of a record could be played by simulating the record needle. Is it possible to scan or photograph a CD at such a high resolution that the pits become visible? Then you have all 2.5GB of the raw EFM right there. If the CD is scratched the lacquer layer could be removed somehow I imagine.

That might be the best option anyway. I heard rumors that the original PlayStation copy protection involved introducing an intentional wobble into the tracks who's frequency is reported back to the application by the CD-ROM controller. Full preservation may necessitate your scheme.
