Well I also realized I have this problem it hasn't affected my gameplay in any way. I have seen countless posts on this subject and people giving advice on how to take care of your disc. I am an adult and sadly i mostly just play black ops so it sits in the xbox more than anything. I have rarely put it back into it's case and have done so carefully when needed so imagine my surprise after reading about all these posts that i thought they just didnt take care of thier stuff that i would find the same thing when i looked at my own black ops disc. This is upsetting that the quality of materials used to make a $60 dollar game + $60 Live subscription to enjoy the game would be so poor.
