Abstract

The limiting capabilities of 3-D holographic memory in terms of storage density and data reading rate are considered. The emphasis is on the problem of the interference noise during data reading. Various designs of 3-D holographic memory, including a multilayer system, are discussed. The possibility to effect superresolution in reading/writing holographic transparencies is shown. Under certain conditions, the storage density can be an order of magnitude higher than that determined by the diffraction limit. The paper also discusses the fields of application of holographic data storage systems with regard to the development of 'bit-by-bit' memory systems in particular systems based on the principles of near-field optics.
