ABSTRACT:
A holographic data storage (HDS) system and method are provided. Generally, the system includes: a light source for generating a coherent light; beam-forming optics for forming the light into collimated object and reference beams; holographic storage medium; a spatial light modulator (SLM) located in a path of the object beam from the beam-forming optics to the storage medium, the SLM having a number of pixels for encoding data to be stored in the medium into the object beam. Preferably, the SLM can modulate both the amplitude and phase of light from every pixel on the SLM. More preferably, the SLM is also located in a path of the reference beam to the storage medium to modulate the phase of the light to store multiple holographic pages of data in the same physical volume of medium through phase multiplexing. Other embodiments are also described.
