The method to record and read multiple data pages simultaneously by multiplexing them in the Fourier domain has been proposed for improvement of the data transfer rate in a holographic data storage. However, there are cross-talks caused by diffracted lights from each data pages, which restricts the number of multiplexing. In this study, the problem is solved by introducing the apodization to input data pages. This approach is confirmed by the numerical simulation.
