I haven't seen them, but my impression is multiple pieces, not just
scratches.  Definitely a job for a specialist, not a do-it-yourself
project.

Yeah, surface scratches on the bottom can generally just be polished off. 
Local defects on the bottom surface are not that bad, because the data
layer is just under the *top* of the disk, so the bottom surface is out of
focus to the reading laser.
