Abstract

Conventional storage technologies such as hard disk drive, compact disc, digitalversatile disk, and blu-ray disc rely on the track-based paradigm i.e. they storeinformation along tracks that are well separated in order to eliminate inter-trackinterference. This storage paradigm is two-dimensional (2-D); however it uses thesecond dimension only loosely. Holographic data storage (HDS), on the other hand,breaks the density bottleneck of conventional storage technologies by utilizing thepage-oriented paradigm that stores information in the form of 2-D holograms. Vaststorage densities are achievable by multiplexing several holograms throughout thevolume of the media. In addition, the page-oriented nature of HDS allows for highdata rates by retrieving the entire hologram with a single flash of light. Thus, HDSis a promising technology for the increasing demands of information systems. In this work we developed channel models and detectors for HDS.
