Well, you copy an image to HDD and burn it as necessary. Otherwise, buy a 100-pack of DVDs and a DVD-RW drive.
If you meant on rescuing data from a disc that was used a mat (or is it pad?) for coffee, I haven't got a faintest clue. Except maybe pay someone loads of money to do some chemistry and extract as much data as they can.
