Well it depends, what kind of scratch is it? If its a big really noticeable scratch you might have to just get a new disc. If its a minor scratch then you could try looking up a few home remedy solution (you can find good ones on wikihow) otherwise man you could maybe take it in a game store and have them buff it, or your screwed and have to get a new disc.

Here is a good, reliable way to fix scratches on a disc (It always works for minor scratches. May or may not work for deeper ones, but it can't hurt anything to try). First, dab a very small portion of toothpaste on your finger and rub it on the backside of the disc. Then, with a very slightly moist rag, gently rub the toothpaste off. Be sure to get every bit of toothpaste off the disc or else it will not able to be read. Once all the toothpaste is off, dry the disc of any moisture with a dry rag until there is absolutely no moisture left. Finally, put the disc into your console and hope it works.
