Abstract

The possibility to use the third dimension of the medium for data storage and extraction in memory devices is accessible in a wide sense only if a holographic method of data recording and reconstruction is used. However, this possibility has many limitations part of which is inherent just to the holographic devices. Among them one can find significant influence of a limited dynamic range, quadratic dependence of power expenses on the amount of stored information, limitations of the number of selective positions which can be used for the hologram multiplexing as well as some geometric limitations which are significant in 3-D holographic memory. On a level with that, such phenomena exercise influence on holographic memory device information capability as diffraction limits of information input and storage, spatial information losses in a complex system, limitations of rate of information input and output in holographic memory devices etc. The limitations caused by each of the listed factors have been compared and analyzed. It has been found that some of these factors do not influence on information capability limitations provided by the other reasons.
