What do i do if my game called Medal Honor Airborne keeps saying to clean the disk?

I mean a few days ago i was playing medal of honor and all of a sudden it says the disk is unreadable. They suggested to clean the disk witha dry cloth. So i did but then it still says it. And my disk was scratch- free. WHAT DO I DO? sell it on ebay then rip off someone then move to new mexico.What do i do if my game called Medal Honor Airborne keeps saying to clean the disk?
