as DervishD already explained, the kernel driver doesn't, but lasers can
easily cause severe irreversible eye damage. doesn't matter if you actually
*see* the laser beam. NEVER use a non-closed cd drive (either standard simple
stereo units or dvd burners, they all present similar dangers). most drives
have hardware safety features that disable all lasers when tray is open, but
some other may not...
