How Do You Fix a Scratched Xbox Game or Cd?

My favorite game was lost, when I found it , it was all scratched up and it dont work, how do I fix it?

Suggestion:

You can buy one of those disk repair kit, which will strip away the top away of the disk so that the scratches are gone. Or you can go to Gamestop or Best Buy and have it fix for you for a few bucks.
