Splinter Cell: Pandora Tommorrow Problems

[Tango87]

Ok I am having a problem backing up my game. I used the data burn method but when I put the disc in it says "The disc is dirty or damaged" so I made a new disc with a different type of media and it still says the same thing. First I used ritek then I used sony. If someone could help it would be greatly appreciated. Thanks in advance. OH yeah I have an Apple X-3 chip i think.
