<P>PROBLEM TO BE SOLVED: To provide a holographic storage medium, and more specifically, a holographic storage medium (10) with an integrated phase mask layer (21). <P>SOLUTION: The holographic storage medium (10) has a phase mask layer (21) on top of a holographic storage layer (22), wherein the phase mask layer (21) has one or more phase pattern areas (25) for coupling-in a reference beam (8) and imprinting a phase pattern on the reference beam (8), and one or more neutral areas (26) for coupling-in an object beam (7) and/or coupling-out a reconstructed object beam (11). <P>COPYRIGHT: (C)2009,JPO&INPIT |
