<P>PROBLEM TO BE SOLVED: To provide a hologram information recording regenerative method for achieving miniaturization of the whole apparatus. <P>SOLUTION: The hologram information recording regenerative method comprises: a hologram information formation process for forming an interference fringe in a direction substantially orthogonal to a recording medium face, by irradiating an information recording area R of a recording medium with reference light and data light from the same direction to the recording medium; a process for forming a reflection film 120 on the surface of the recording medium 100 of a side of irradiating the reference light and the data light; and a hologram information regenerative process for regenerating hologram information, by irradiating the reference light from the light not forming reflection film 120 to the recording medium 100. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
