|Clean it as best you can and then try it in another computer just to see if it'll read it. You may be able to copy it.|
There was something you could buy that would polish the disk and remove the scratches. (I tried to use a buffing pad on a drill once. Don't do it. It worked until I spun it too fast--which was easy to do--and the disk plastic melted.)
Or check the support page for you model. You can probably order a new disk.
The data is on the label side of the disk and the clear plastic just protects it. If the scratches are on the label side there's probably nothing you can do.
