Did someone on this net really say that cd-player optics
don't need cleaning because the laser burns the dust
off the optics?  How can this be?  To do that you need
megaWatts of power, and you have to focus.  The diddy little
diode in there certainly won't do that.  Also, the dust
is on the optics, where the light is not focussed.  Also,
if there's enough power to burn dust off a lens, then that
litte explosion leaves a defect on the glass surface with
a lower breakdown threshold, which then gets damaged itself.
