Won't Eject CD

I have a iBook G4 and i put in a cd to try to load it to iTunes, but now it wont eject. It didnt ever even show up on the computer. I pressed the eject button, I looked in Finder, I trieed everything but nowhere does it acknowledge there is a cd in the drive. It is a dualdisc and has dvd on one side and music on the other, so maybe it has something to do with that?
