I would think they are just covering their butt. With all the different colors of CDR's that are out there, some lasers dont know what to do with them. Say, you have a blue-backed CDR. When a red laser bounces off of it and it hits the receiving portion of the CD player, it is kind of a purple color, that particular CD player doesnt know what to do with a purple data signal, its looking for red. I've seen a few that will play mp3's when they arent designed to do so.

My educated guess...

Your pretty much dead on there bull.

My Nakamichi isn't spec'd out to play Mp3's, but it does. It also says that it isn't compatible with CDR(-W) formats either, but it does with most.


They are totally just covering their ass. The oem optical device is built to cover a certain range of wavelength, and nothing more. If your Mp3's are within that range, bully for you!

Yup, the whole CD design stemmed from the record player (yeah, you know the vinyl 12" discs your parents have stuffed away in the closet). They used a needle that scratched across "analog" 1's and 0's and made music using the high points and low points stamped into the vinyl. The CD does the same thing just digitally.
