Mine had been jammed for a few months, I just didn't have the time to take it apart. Usually when one gets jammed, I can use a credit card and pry it up, then it will spit out.
However this time, the CD tray had already gone down. You can take the gray sleeve off, there should be several star point screws that you can take out. The sleeve kinda snaps together, just carefully snap it apart, and locate the jammed CD.
The CD tray should be able to be lifted up a bit to allow you to slide them out of the load eject slot. If you have to, use the gear that is attached on the right side (IIRC) near the load and eject slot.
NOTE: I would pull them all out to ensure that you got the right one.
The track and tray are operated by tiny components, so be very carefully if you are trying to force anything, those tiny parts can be impossible to find if dropped, or even broken.
