I suspect that a laser turntable would find serious application in conservation work like this.

Those celluloid film laminated to a glass are "acetates", and one can only hope that Laser Turntable is the only solution for them.

Unfortunately not - it can play only black coloured flat records, for all other material, it will produce large skips.

I think you can visually scan the surface of any physical medium to a computer, and converting the image to wave forms is not terribly difficult.

No need to track the surface in real time.

Nice!

Interesting info - thanks!
Academic for the time being though - the acetates have gone to an enthusiast who is going to get them restored by a specialist.
