*** Your drive may need cleaning. Cleaning kits can be purchased from any store that sells CD/DVDs. ***

Does your Superdrive accept the media? If so, maybe the lens should be cleaned or try quality media such as Verbatim (Macs are finicky about which media works). Or, the drive could be malfunctioning - vertically installed drives are not known to be error free or reliable.
