We propose a volume holographic storage scheme, spatioangular multiplexing, which is a hybrid of both angular and spatial multiplexing. We describe the recording procedure, for a preliminary experiment in which 750 holograms were recorded (at room temperature) in a single photorefractive crystal of iron-doped lithium niobate and report the successful replay of all images with negligible cross talk and with an average diffraction efficiency of 0.5%.
