1. A light-transmissive data storage sandwich apparatus for storing digital data in an optical data storage medium layer, the device comprising:
a set of monochromatic light sources of preselected wavelengths;
a diffusing layer, coupled to the set of monochromatic light sources, configured to uniformly distribute light from the light sources;
a beam directing layer having a rear surface, the beam directing layer coupled to the diffusing layer, configured to redirect light from the diffusing layer in a direction perpendicular to the rear surface;
a pixel selector layer, having an rear surface, the pixel selector layer coupled to the rear surface of the beam directing layer and configured to define a set of masks that selectively inhibits transmission of light, on a pixel-by-pixel basis, at a wavelength of interest; and,
the optical data storage medium layer applied to output surface of the pixel selector layer.
