Abstract：
 This invention is in the field of optical information storage and volume holographic data storing process. It relates to a nonvolatile volume holographic data storing method. It used the photochromic material as the volume holographic recording medium. It realized the data information rapid recording, nonvolatile reading and multiple repeated erasing and writing by the two-photon recording, single-photon reading and ultraviolet light erasing. This invention increase the volume holographic storing density of photochromic material.
