Abstract
According to one aspect and example, a method for recording holographic media and/or holographic master data masks includes recording at least a first hologram or information layer with a first holographic medium (e.g., a 'submaster') and recording at least a second information layer with a second holographic medium (e.g., a second 'submaster'). The first information layer and the second information layer from the first and second holographic media are then sequentially reconstructed and stored with a single holographic master medium (e.g., a “master”). The holographic master may then be used to record the stored first and second information layers into additional holographic media, for example, into HROM devices or the like.
