I restore antique and not so antique pinball machines. The most difficult part is the cosmetics of the backglass art work, as the ink often flakes off the glass.
I have perfected a method of scanning in portions, often six or nine segments, of the glass and then "stitching" them together using software. I have done several 300 dpi images this way and manage to get them within a pixel or so.
A larger disc can be scanned in segments, with joining indicators marked. Then the multiple images can be carefully joined into a large image. The only problem is the labor intensive nature of the process.
Let me know if you need more details.

The finished image of the pinball machine art is either 17x17 or 19x19 inches square, at 300 dots per inch. He says he uses one of the popular image manipulating programs used by artists for computer graphics manipulation.
