Methods and systems for recording to holographic storage media

A method of storing holograms in a target medium, the method comprising:

• recording multiple holograms in each holographic medium in a set of N holographic mediums, wherein the multiple holograms include partially spatially overlapping data page holograms and N is greater than 1;
• sequentially illuminating the each of N holographic mediums with a reference beam to reconstruct the multiple holograms in the each of the N holographic mediums and record the reconstructed multiple holograms to the holographic master medium, wherein:
• the multiple holograms in the each of the N holographic mediums are reconstructed and recorded in parallel to the holographic master medium;
• the reconstructed multiple holograms from one of the N holographic mediums and the reconstructed multiple holograms from another of the N holographic mediums overlap in the master holographic medium by use of one or more multiplexing techniques selected from the group consisting of angle, wavelength, confocal, fractal, phase code, and peristrophic multiplexing;
• illuminating the holographic master medium to reconstruct the multiple holograms from the one of the N holographic mediums and record the reconstructed multiple holograms from the one of the N holographic mediums in the target medium;
• and
• subsequently illuminating the holographic master medium to reconstruct the multiple holograms from the other of the N holographic mediums and record the reconstructed multiple holograms from the other of the N holographic mediums in the target medium.

A method of preserving dynamic range in a holographic master medium, the method comprising:

• sequentially recording first multiple holograms to a first holographic medium, wherein:
• adjacent holograms of the first multiple holograms partially spatially overlap each other;
• and
• the first multiple holograms consume a dynamic range first quantity in the first holographic medium;
• sequentially recording second multiple holograms to a second holographic medium, wherein:
• adjacent holograms of the second multiple holograms partially spatially overlap each other;
• and
• the second multiple holograms consume a dynamic range second quantity in the second holographic medium;
• reconstructing the first multiple holograms from the first holographic medium in parallel and recording the reconstructed first multiple holograms in the holographic master medium, wherein said recording the reconstructed first multiple holograms in the holographic master medium consumes less dynamic range in the holographic master medium than the first dynamic range quantity;
• reconstructing the second multiple holograms from the second holographic medium in parallel and recording the reconstructed second multiple holograms in the holographic master medium, wherein:
• said recording the reconstructed second multiple holograms in the holographic master medium consumes less dynamic range in the holographic master medium than the second dynamic range quantity;
• and
• said recording the reconstructed second multiple holograms in the holographic master medium includes multiplexing the second multiple holograms with the first multiple holograms by use of one or more multiplexing techniques selected from the group consisting of angle, wavelength, confocal, fractal, phase code, and peristrophic multiplexing.
