you must be able to guarantee that in case of failure the beam is safe. 
If a failure occurs, you simply cannot guarantee the DVD laser will 
shine at most 20mA or wse. In case of failure it can shine at 200mA and 
this can be dangerous. Then handling such dangerous part in DIY is 
pretty dangerous. You should be using anti-laser glasses all time etc.
