[Robotgroup] CD/hard drive hacks?

[brooksdesign]

  I just sent a more focused description while you were replying, but yes this is what I want. But let's say I want to take an old cd burner, what KIND of interface? I guess I would need a part number for the head so you could track down the specs or are they mostly all the same?
