In the thesis, we made an improvement for our off-axis volume holographic optical system. The mathematical model is also derived to simulate the system. Based on the model, we calculated the cross-talk effect and bit-error rate of the multiplexing recording system in tangential and radial directions. We also proposed a new concept that we use multiple spherical waves as the reference beam to reduce the diffraction efficiency of the noise page during disk rotation. In the end we estimated the system capacity and optimized some parameters to improve the capacity and reading quality.
