We need to know more information about it. Also, you do realize CD drives are infrared correct? You can't see it (well, not very well anyway) and that makes it 100 times more dangerous than visible light lasers. What appears to be a dim red light is actually a very powerful IR beam. It's very easy to make a mistake with something that's invisible.
