Try '''holding the trackpad down at power on -''' the disk should eject.
If that fails try '''the double sticky tape method''':
# Get an old CD/DVD and some thin double sticky tape (like scotch tape ~3/4in wide).
# Put a couple of strips close together on one edge of the CD/DVD,
# Firmly hang on to the CD/DVD and angling the disk put it part way into the slot TAPE SIDE DOWN.
# Rotate the disk flat. (You want to try to snag the disc with the tape, so that you can pull it out)
If that doesn't work time for mayer's solution.
''If this answer is acceptable '''please remember to return and mark it'''.''
