Angle-multiplexing hologram reproduction device, and method

A hologram recording device (100) includes recording angle modification means (19) capable of relatively modifying the recording angle of a hologram recording medium (200) with respect to signal light (L3) and reference light (L2) and control means (18). The control means sets a recording angle for recording a specific angle recording surface as a reference recording angle among a plurality of angle recording surfaces on the hologram recording medium. Furthermore, the control means controls the recording angle modification means so as to modify the recording angle after the setting by a predetermined angle each time against the reference recording angle.
