wow, and here I thought words like that would be censored!
yeah, I've heard the same thing about the trays... I don't know. Scientifically, there *IS* some basis for it, but I don't know how much it really effects things. Actually, generally speaking, I've found the black CD-Rs MUCH harder to read, even if their quality was good.
the idea goes somthing like this: The laser used to read the pits and lands is a little wider then the track size, this means that some of the light reflected will be useless garbage, and some of this will eventually make it back to the read head via reflection. This causes minor problems for the reader, but generally nothing big. Supposedly it is mainly car stereos that have the biggest problem with these errors. Using Black CD-Rs decreases the amount of reflection, and therefor decreases the amount of light that is reflecting garbage data. More light will reflect from the actual track because of the angle of the laser, and in the end there should be a lower ratio of garbage data to good data.
like I said, it makes sense, but I don't know if it really makes a difference.
