Claim 11:
12. The holographic data storage system of claim 11, wherein multiple second multimode optical waveguides of the reference waveguide network are optically coupled a first multimode optical waveguide of the reference waveguide network at different locations along a side surface of that first waveguide, said multimode optical waveguide of the reference waveguide network being one of the second waveguides of the reference waveguide network, wherein each of the other second waveguide(s) of the reference waveguide network also has a plurality of out-coupling regions optically coupled to:
the respective further recording regions of the holographic recording medium, or
the respective recording regions of at least one further holographic recording medium, the controller configured to control the at least one optical characteristic of the reference beam or the at least one guiding element of the reference waveguide network to cause the reference beam to be guided from the in-coupling region, via the first waveguide of the reference waveguide network into to any one of the second waveguides of the reference waveguide network, and to any one of the out-coupling regions of that second waveguide.
