Sometimes the optical drive is still functional but needs a clean up to do efficiently his job. When there's dust (or if you smoke, tabaco fume residue) on the laser lens the laser beam may not correctly read the disk and the result is that the optical drive will spit it out. So if your intention is to replace the optical drive yourself you could open the optical drive (4 screws) and clean the laser lens with a Qtip and alcool (apply a very small amount of alcool on the Qtip and clean the lens without applying too much pressure on it then dry the lens with the other Qtip end). It's also a good occasion to clean the optical drive mecanism with compressed air and check if the black textile protection at the entrance of the drive is well glued in place.
