+*Here is a way to get the disk out without ruining the disk drive, or the disk.*+
+*Restart the Mac, when the grey screen comes, hold down the mouse button, this may take a while, but the disk should come out.*+
While this works fine for standard discs that won't eject, the problem here is with a mini-disc. The internal hardware of the drive simply does not support the smaller disc... so it basically "falls" into the drive. The eject mechanism can't eject it.
