Claim 9:
10. The holographic data storage system of claim 9, wherein multiple second multimode optical waveguides of the input waveguide network are optically coupled to a first multimode optical waveguide of the input waveguide network at different locations along a side surface of the first waveguide, said multimode optical waveguide of the input waveguide network being one of the second waveguides, wherein each of the other second waveguide(s) also has a plurality of out-coupling regions optically coupled to:
respective further recording regions of the holographic recording medium, or
respective recording regions of at least one further holographic recording medium, the controller configured to control the at least one optical characteristic of the input beam or the at least one guiding element of the input waveguide network to cause the input beam to be guided from the in-coupling region, via the first waveguide into to any one of the second waveguides, and to any one of the out-coupling regions of that second waveguide.
