Micro-hologram multiplexing method was proposed and researched; it allowed to increase data writing and reading speed. This method was implemented in the developed and tested system. The ability to multiplex holograms, with the usage of multichannel write head, and simultaneous reading of those holograms with the usage of multichannel read head, was shown. The advantages and the perspective of this method and developed optical system usage for creating multiplex holograms in the systems of archival optical-holographic memory are listed below. The first is the elimination of need for mechanical motion of system elements both when multiplexing on the stage of writing and when restoring of multiplex holograms. The second is the absence of crisscross interference in the beams, restored from multiplex holograms. And last, but not least, it is the ability to use relatively thin recording environment for the writing.
