I got a walkman that did that to disc one of my police box set... fuckin sucks!! I stopped using it immediately.

as for your scratched cd I heard furniture polish works, or maybe one of those overpriced cd repair kits at certain record stores. I've tried neither personally, I would strongly recommend finding a similar audio cdr (or cd you don't like lol) and scratch it similarly, then try to "repair" that before you go to work on your one-of-a-kind disc. Or, if your disc isn't one of a kind track down another copy.
