Different type of CD. Back then they were analog. As long as the media is digital any kind of conversion is possible. Many banks still have very old records on 9 track tapes, and they are still surefull.

CDs have never been analog. The underlying data structure
introduced in 1984 is digital.
this is what we are going through at my work, i run a film room for a spinal surgery and research facility. we have hard x-ray films back to the 1910s in storage and are paying dearly for the storage of them. we are continually looking for better ways of maintaining our films especially now that pretty much all films are going to be on cd or other form of media. films on CD that were taken a few years ago are all but impossible for us to bring up on our monitors much less get a clear enough image for our surgeons to use.
