COLLINEAR HOLOGRAPHIC DATA STORAGE USING ANGULAR MULTIPLEXING METHOD

摘要

The present invention relates to a holographic data storage device using the angle multiplex system of the collinear method , in particular collinear (collinear) is applied to the system alone angle multiplexing method in that Papik storage device , to an apparatus for increasing the storage capacity many times over . Holographic data storage apparatus using the collinear method of the present invention includes a spatial light modulator that is controlled by the reference light split by zone . According to the present invention , making the compatibility with the existing optical storage device such as a DVD of the simplicity and advantages of the system while a collinear manner , and can increase the storage capacity of the system as many times more than that existing in its own way out of the conventional method alone can constitute a graphic data storage .
