I found this press release just yesterday and I'm curious to know how it works:

In Figure 1:
-Substrate 2 is just a protective cover for the cd.
-The photo polymer is the recording layer, but which wavelength(color) is actually causing the polymerization for writing? And which one is reading the hologram?
-The gap layers are just there to separate the dichroic mirror.
-The dichoric mirror is basically a wavelength filter that either reflects light or allows light to pass through.
-Substrate 1 is just the shiny part of the cd that prevents the light from escaping. Why does the aluminum reflection layer have pits?
