Madden 13 disc is unreadable??????????????????????????????????????????????

I got Madden 13 for christmas yesterday and i was really excited because i love the madden series i started it up and played 2 online games for about an hour then i took it out I tried playing it later started it got to the team selected advanced to game and then while loading the game it says the disc is unreadable, so i tried it like 5 other times still didn't work, i tried playing using my friends madden on my console and the same thing happened he said his game worked on his 360 so i went over there and tried my madden on his system and it worked

Is there something wrong with my xbox and the game or what , all of my other games still work right so......
