If the disc is damaged then you can probably try repairing it. Of course if you burned the CD while it was damaged then there's virtually no hope of recovery, even if you restored the CD. I would also heed james.miller's advice and try the CD in another drive. I had a 8x DVD-ROM drive that would constantly choke on CDs and make a number of read errors, even when there was nothing wrong with the disc. From your description though I think it's most likely that the disc is bad.
