/* No cleaning - the laser beam destroys dust motes */

Really? I hadn't realized that the beam was that powerful, or remained
focussed in one spot for long enough, to vapourize the dirt.

But what about lint and hairs? A local radio station (CFNY) regularly
has mistracking problems with their CD players, and it seems that wiping
the surface of the disc (and/or using canned air (Dustoff)) eliminates the
problem.

Whatever the case, it cannot hurt to keep the unit clean. The optics unit
is most likely sealed to keep out contamination, yet foreign objects are
bound to be picked up around the laser 'window'. Would it do any harm
to use a cotton swab and alcohol to clean the 'window'?
