CD and DVD are fragile media. A few scratches here and there and they can easily become coasters on your table.
Scratches that are perpendicular (going from the center outwards) are generally less harmful or damaging than the scratches that go along the spiral. So if your CD/DVD has more of the latter ones, then the chances of recovering data from that CD or DVD may be bleak.
There are some ways to try to recover files from scratched medias.
Usually the best outcome is produced using combine techniques of hardware repair and specialized software to read and recover the data.
If you are not sure about performing the repair by yourself, just pop in.
