Abstract:
An apparatus for reading from and/or writing to holographic storage media is described, and more specifically an apparatus for reading from and/or writing to holographic storage media with two or more reference beams that overlap inside the holographic storage medium for reading and/or writing a single hologram. The two or more reference beams are mutually incoherent during reading and/or writing.
