Paper Abstract

Holographic data storage (HDS) is a promising technology that has huge capacity. A multiplexing method plays a significant role in increasing the data capacity. Various multiplexing methods have been researched so far. In this paper, we proposed shift-peristrophic multiplexing using spherical reference wave and experimentally verified that this method is efficiently increase the data capacity. A series of holograms was recorded with shift multiplexing and rotating recording material with the axis of rotation being perpendicular to the material's surface. This method can realize more than 1 Tbits/inch2 data density recording. Furthermore if we maximize the performance of a recording medium, several TB per disk capacity would be available.
