yes, i have blacks, can someone explain to me why they're considered so good (or are hyped up to be so they can charge lots for them?)

well, blacks (from my experience) have a tendancy to play in more devices that are picky, but I don't know why. They don't use any special dye type, they use the normal Phthalocyanine and Cyanine dyes (maybe Azo too??). But they can be just as poor in quality as any other type of CD-R, so as with everything else, don't judge a CD-R by it's colour

I allready explained this once.
Black cd-r's and most (METAL) AZO disc's to have the big advantage that they cause less significant amount of stray laser light bounced around the inside of the CD itself. This stray light eventually finds its way back to the pick-up assembly, creating jitter.
More jitter means more problems.
HOwever things can also work differently.
The disc reflectivity can be to bad with the dark disc's and even normal cd-r media and then the media which reflects best is the best option. High reflective media is made by
Now this problem happens more with AZO media then black cd-r's. Strange would some people say since black absorbs more. But pthalocyanine is as a dye easier to read/write (less energy, but more error sensitive) as AZO.





So the best sollution for compatibility would be
1 A very reflective layer
2 A very low energy dye (MITSUI)
3 Black Polycarbonate.
