my slot loading Drive

Okay, so by accident, I think I put that clear disc they put on top of a new spool of DVD's in my ibook. Now it won't read or it won't eject. Whenever it's about to eject, it makes a wierd sound and it goes back in. Is there anyway to get it out without opening up my computer?

Have you tried rebooting and pressing a holding the mouse button while the system boots?

yeah, I tried it, it does nothing. It keeps sounding like its about to eject, except instead of coming out it goes back in.
