Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

To repeat an earlier post of mine, does it rely on surface plasmon resonances for light absorption through the utilization of specific nanoparticles tuned to absorb specific wavelengths or frequency ranges?

And since it’s the nanoparticles doing the work, the color of the nanoparticle impregnated material does not need to be black. Did I win?? Did I win??

Close enough!! A for effort! PM your shipping address. 

The facts that (1) there’s a threshold of detection for the photodector and that (2) the Red Book committee hired “coding experts” Reed and Solomon, a couple of older conservative types, to come up with some hairy far out error detection/correction codes leads me to believe the original designers knew of this design flaw - scattered background light - but chose to ignore it and cover it up. Another possibility is the reason for the detection threshold was because they knew the light wave cancellation when the laser beam was over a “pit” was not always absolute, that some light would be returned. Or, it’s possible they were just plain ignorant of the problem.
