Forsooth.
Ok, thanks for the explanation.
What is Dark Matter for CDs?
Dark Matter is a spray on thin film the active ingredient of which is an absorber of the invisible portion of the CD laser background scattered light. Everyone is of course familiar with the green pen for CDs that absorbs the red portion of the scattered CD laser light. As it turns out most of the scattered laser light is not in the visible red portion of the spectrum, since the wavelength of the CD laser is 780 nm, into the near infrared portion. Thus green cannot absorb much of the scattered light since the invisible infrared portion is not affected by color, green or any other color.
