<P>PROBLEM TO BE SOLVED: To provide a reflection type collinear holographic storage system 1 in which an improved overlap between an object beam 15 and a reference beam 2 is achieved. <P>SOLUTION: The collinear holographic storage system 1 has spatial light modulators 14 and 22 for imprinting a data page on an object beam 15, which is located in the beam path of a portion 10 of a reference beam 2 transmitted through a holographic storage medium 9, whereby the object beam 15 is generated by imprinting a data page on the transmitted reference beam 10. The diameter of the reference beam 2 in the holographic storage medium is matched to the diameter of the object beam 15. <P>COPYRIGHT: (C)2009,JPO&INPIT |
