Title:

METHOD AND SYSTEM FOR RE-WRITING WITH A HOLOGRAPHIC STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2010/148280

Kind Code:

A3

Abstract:

A method and device for re-writing data on a holographic storage device is disclosed. First and second electro-optic modulators may phase shift the reference and data beams used to store data on the photorefractive crystal. When the reference beam is shifted 180° out of phase with respect to the data beam, the photorefractive crystal is erased.
