<P>PROBLEM TO BE SOLVED: To provide a holography recording apparatus, reproducing apparatus and method therefor by which information data recorded in a holography medium can be fast read out in a simple configuration. <P>SOLUTION: The holography reproducing apparatus includes: a reference light irradiating means which changes the angle of reference light to irradiate a holography medium every second variation angle determined by dividing a first variation angle corresponding to an information data page where the information data are to be written by a predetermined division number, which assign a information data page region corresponding to the first variation angle to blocks divided by the division number, which reads out the multiple-recorded information data as a divided sub data of the information data, and which irradiates the medium while sweeping the angle of the reference light; and a data detecting means which is made incident reproducing light from the holography medium and detects the information data from the reproducing light. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
