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'? -=-=-=-= sjk.
