ABSTRACT:
A system and method capable of providing high data rate data copying and recording in holographic data storage while maintaining the copied data's signal-to-noise ratio. This is achieved by using optically-based parallel signal processing. In one preferred embodiment, the present invention uses a plurality of optical resonating cavities to provide thresholding and gain functions via positive feedback.
