Abstract
A hologram recording apparatus () includes a record angle change device () capable of relatively changing the record angle of a hologram recording medium () relative to signal light (L) and reference light (L); and a control device (). The control device sets a record angle for recording a specific angle record plane as a standard record angle among a plurality of angle record planes on the hologram recording medium. Furthermore, the control device controls the record angle change device so as to change and fix the record angle after then by a predetermined angle from the set standard record angle.
