A hologram recording device that records a hologram by passing recording light and reference light through the same objective lens and irradiating a recording medium, includes: a light splitter for dividing light from a light source into the recording light and the reference light; a light combining member for combining the recording light and the reference light, which have been divided by the light splitter, so as to be coaxial, and causing these light beams to advance to the objective lens; first and second lenses, positioned on an optical paths of the recording light and reference light, between the light splitter and the light combining member; a first aperture that narrows the recording light which has passed through the first lens; and, a second aperture that narrows the reference light which has passed through the second lens, the first and second lenses being configured to have different optical magnifications.
