After all, the track is physical, and a small camera/microscope rig should get enough information to reproduce the sound.

I think those are called CDs.

Very close, but not quite. A CD player uses a laser to check refraction patterns to read a digital signal from...I'm simplifying, but it's sort of a sequence of mirrors and holes, on and off. I'm suggesting "scanning" the grooves like we do comics, then using some analysis to reconstruct the sound as if a needle was vibrating in it. Similar mechanism, different principle, basically.
Plus, you can't shove a cylinder or an old LP into a CD player. If you want to listen to the music, I mean.
Not only would it be a non-destructive read, but the playback could simulate different kinds of needles and possibly even try to "heal" damage that's been done previously. I mean, the best use for such a thing would obviously be preservation.

OK, I thought you meant bringing back cylinders for some reason. Yeah, preservation is important and each handling further damages the source, just like magnetic tape degrades with each playback across the magnetic heads, or even physical handling of books.

Just what I meant, John, and the concept of making new ones could be "tweaked" using new materials that would outlast all of the originals. In fact, a duplication process that used only physical molds and copies might also preserve the fragile originals. I've been trying to figure out something with my Doré wood-engraving that would allow me to make a mold and print from that rather than risking damage or wear to original wood. When I get more time... ha ha ha. But, really, wouldn't YOU want to have a print from such an original block?
Peace, Jim (|:{>

Just tossing around ideas so I don't forget about this, a high-resolution scan would probably be a good place to start. Hand it off to someone with the skill and patience to vectorize it (or build it in a CAD program), and you can push that to a CNC router or laser engraver.

While you would get the closest picture, it would not be from the original wood. To me that would be no different from an analog to digital recording. To be an original wood print, without damaging the wood, would require coating the wood with something that would protect it without removing any detail. Then you could say you had original prints.
