Replace the drive, there is very little you can do in repairing any cd/dvd drive these days. Hopefully it's a desktop drive and will only cost you $20 or so to replace.

it is not sitting flat maybe or what ever it is sitting on is not stable (wobble) which makes the disc that is spinning very fast wobble and scratch it. you should hear it when it happens. should sound kida like dragging your feet with sneakers on.

make sure the screws are long enough and tight
