Claim 7:
8. The holographic data storage system of claim 6, comprising an output waveguide network, formed of one or more further multimode waveguides, the output waveguide network having multiple in-coupling regions, each of the multiple recording regions of the holographic recording medium also being optically coupled to a corresponding one of the multiple in-coupling regions of the output waveguide network for receiving an output beam therefrom, and an out-coupling region for providing an output beam to the detector array, the controller coupled to at least one of:
the emitter system for controlling the at least one optical characteristic of the reference beam, and thus at least one corresponding optical characteristic of the output beam, and
at least one controllable guiding element of the output waveguide network, the controller configured, in said read interval, to control the at least one optical characteristic of the reference beam or the at least one guiding element of the output waveguide network to cause the output beam to be guided to the detector array, wherein different ones of the recording regions may be read from using the same detector array, whilst the in-coupling regions of the output waveguide network remain at fixed locations relative to the recording regions of the holographic recording medium.
