We report azo functionalized copolymer film as a hologram recording material for high-density information recording and retrieval. A polarization-angular multiplexed method can successfully record and reconstruct 6 images on the same area of the film. Similarly, a vector-vortex beam can also be successfully reconstructed simply by illuminating a the hologram with a collimated laser.
