Yeah. I had an automatic version. It was basically a pair of ultra-fine sandpaper wheels, and some buffing wheels for a finishing pass. The wheels would spin while the disc slowly rotated, using the ultra-fine sandpaper to remove the surface layer of plastic (where the scratches were) and then the buffing pads would smooth things over a little bit so the surface was smoother.
It definitely still left circular buff marks all over the surface of the disc. But it at least helped get rid of the random scratches that would cause discs to fail to read.
