Paper Abstract
Along with the wider use of high-speed information networks and multimedia, it is increasingly necessary to have
higher-density and higher-transfer-rate storage devices. Therefore, research and development into holographic memories
with three-dimensional storage areas is being carried out to realize next-generation large-capacity memories. The
mainstream in the world is the angle multiplexing method, however, its beam position control is quite severe. In such
situation, we study about shift multiplexing method because it costs not much and its control is easier than the angle
multiplexing. In this experiment, we examined shift selectivity of track direction, radial direction and vertical direction of
the medium. As a result, combining these different kinds of selectivity, we found a possible multiplexing way to achieve
several tera bits per inch square density recording.
