We propose a method for directional control of the shift selectivity of the speckle-multiplexed holograms using the holographic diffuser whose surface profile varies with the orthogonal direction. The method improves the tolerance of the spatial multiplexed holograms for the repositioning error in the holographic storage. In addition, we utilize the nature that the shift selectivity in the propagation direction of the reference beam is intrinsically relaxed, and experimentally implement the spatial arrangement of the multiplexed holograms in both the "controlled" and the "intrinsically relaxed" directions. We show that the high quality output is obtained using our method by the measurement of the BER of the data-pages that are retrieved from the spatially arranged multiple holograms.
