Abstract
A method and system for bulk erasing in a holographic storage system is disclosed. The method may involve illuminating the entire volume storage region of a photorefractive crystal with a laser to achieve bulk erasure, or may involve selective erasure of a portion of a single written page. For bulk erasure of the entire photorefractive crystal the use of a separate laser or an incoherent light source is used.
