Is it possible to repair CDs?

No. Its not possible. Cd's use random magnetic memory,the PS2 Cd's wont last more than 6 months even if you take good care

If you just bought it try taking it back and telling them its damaged within 14 days they should just give you a replacement. As for repair, cds are made by burning the patern into the disc so a little scratch or mark will send the reading laser off somewhere else and create an error, for some scratches it is possible to "polish" the disc using a special cd polisher, quite a few shops offer this service now. if its deep then no there wont be enough left when its finished.

While compact discs (CDs) are remarkably durable, it’s nearly impossible to prevent scratches and scuffs from occurring from time to time, especially with frequent use. The resulting damage can mean either a skip in your favorite music track or, in the case of data CDs, the loss of that spreadsheet you worked on for two weeks. Don’t despair — repair! While commercial CD repair kits and CD refinishing machines are available, you may be able to repair the damage on your own with products you already have.

sometimes lightly rubbing dish soap into the disc and then wiping it dry will help repair minor scratches, but it's by no means gaurunteed. If you just recently bought it then I would just take it back to the store and demand they give you a new disc.

Is it scratched? If not there are other issues with the PS2. If it is you can purchase a CD/DVD disk cleaner at most good computer stores. They use an extremely fine abrasive an a polisher to repair.
