We investigate angle-multiplexed volume holographic memory with spherical reference beams, for which the spherical approximation is made to model the wave-front distortion in general. We find that the angular selectivity and the cross-talk noise with spherical reference beams are close to those with planar reference beams. The results indicate that angle-multiplexed volume holographic memory can be realized in compact systems for which large wave-front distortion is expected.
