To provide a hologram recording device wherein optical axes of two laser beams distributed with easy composition is stabilized and a hologram can be recorded at two places with high precision and efficiency.

This hologram storage device arranges a half-wave plate 25 to be rotatable about an optical axis in an incident light path of a polarized light beam splitter 26; makes it possible to selectively distribute the laser beam L1 for recording the hologram into different two light paths L3, L4 by the beam splitter 26 and the half-wave plate 25; places the hologram recording parts 29, 30 in each of the two different light paths; and alternately records the hologram by the hologram recording part.
