Abstract: A hologram recording device includes a light outputting unit, which sequentially outputs laser beams having different wavelengths such that the laser beams are coaxial and includes an optical member and laser beam sources, and a recording unit, which sequentially irradiates the recording medium with the laser beams to record holograms in a multiwavelength superimposing manner. The optical member includes optical elements that reflect, in the optical direction, a laser beam incident thereon in a direction crossing the optical axis direction, and that allow a laser beam incident thereon in the optical axis direction to pass therethrough. The laser beam sources radiate laser beams to the optical member, and are arranged so that a laser beam emitted from a laser beam source among the laser beam sources that exposes a recording medium for a longer exposure period with the laser beam passes through a smaller number of optical elements.
