Black CD's

Which Black CDR's do you find sound best and where do you buy them?

Got some at either Walmart or Target,sorry I dont remember,too long ago.I would not rate them better than any others I've used,Bob

Back when there were discussions of the RealityCheck CD duplication system, these ProDisc Black CDR were alleged to be the same discs sold by the creator of RealityCheck.

I bought these, and they are relatively inexpensive @ $21/100. One side is silver, so you can write on it with a black Sharpie pen.

I have not done any comparisons between these and other black CDRs.

I did compare other black cdrs with the ProDisc that I got from RealityCheck and preferred the ProDiscs. Recently, however, on the strong recommendation of others I have decided to buy Mitsui/MAM-A 80m Gold Thermal cdrs, but I have yet to do so. I am thinking of going to a hard-drive digital system which would mean I would not need copies. I presently copy all my cds and extensively treat them.

"Black" means that light in the visual wavelength range is absorbed (None reflected). However, at the wavelength of the CDP laser the disc must be reflective.

By the way, the laser light striking the CD is always reflected. However, the "pits" in the CD surface are 1/4 wavelength deep so that the light reflected from the bottom of the pit is out of phase with the light reflected from the CD surface, and cancels so that it looks like no light is reflected.
