Not sure what you're doing, but the manual eject doesn't require power. When you press it, the front should pop open by a few millimetres so you can then pull the tray all the way out.
If that doesn't work, undo the screws on the casing of the drive (which will invalidate any warranty), and dismantle it to recover the CD. Its very easy to do.

Also how much does a double layer dvd/cd burner/reader cost?
I'm in the UK and can get one for £15.
