You could try one of those drive cleaning discs with the little brush on them, or spraying some compressed air into the slot - in case there is some dust interfering with the lenses. There are multiple lasers for reading and writing the various media (CD, DVD, DVD-DL). But this sounds like a laser has failed in the optical drive - if it is still under warranty, I would take it to Apple for repair. If not under warranty, it might be more cost-effective to get an external burner.
