problem with superdrive

my macbook pro will not give me a cd back it spins every so often and is recognised on the desktop but when i press eject on the keyboard the symbol comes up on the screen but nothing happens!? ive even tried clicking on the eject cd text but nothing happens any ideas!? Thanks

If i try to shut it down it wont shut down and just stays with my desktop background there until the battery ran out its now back on still wont let me eject the cd and when i got to itunes just has the multicoloured symbol spinning! but has the cd tracklisting displayed!

Have you tried right clicking on the symbol on your desktop and selecting Eject?

If all else fails, have you tried starting Disk Utility and ejecting from there? I have a Zip drive where this later is needed more often than not to get the disk to eject.

If you haven't fixed it yet, you might try restarting your computer and holding down the mouse button. This should eject any disk in the superdrive.
