Playing a CD doesn’t require degrading it in that sense, though I’d expect ordinary wear and tear, occasionally dropping a disc and scratching and such to be a factor in the real world.
To backup a vinyl can you just… take a mould of it and recast it? Or some sort of machinable gcode for a CNC? Never come across any vinyl preservation info
People preserve vinyl mostly by just digitizing it. If they want more copies they normally try to find the original master recording and make new presses from it.
Trying to take a mould of the existing disk would make a really low quality copy, and only make the imperfections even worse.
Vinyl just wears out over time as you use them. CDs aren’t really affected by use.
