Abstract
A reflection type collinear holographic storage system is described, in which an improved overlap between an object beam and a reference beam is achieved. The collinear holographic storage system has a spatial light modulator for imprinting a data page on an object beam, which is located in the beam path of a portion of a reference beam transmitted through a holographic storage medium, whereby the object beam is generated by imprinting a data page onto the transmitted reference beam. The diameter of the reference beam inside the holographic storage medium is matched to the diameter of the object beam.
