Hologram recording device and hologram recording method

Irradiates a recording beam (S) at a fixed angle of incidence with respect to the hologram recording medium (B) ([theta] s), the angle of incidence to the hologram recording medium (B) a ([theta] r) variable control while recording light (S) reference light (R) is irradiated to the irradiation site (p), a holographic recording apparatus for multiplexing recording holograms, with leads to the irradiation site (p) by reflecting the reference beam (R), the reference light (R angle of incidence) and (at least one variable reflecting means is oscillated in a predetermined axial (x) around to change the [theta] r) (10), a variable reflecting means (10) are swung in unison , larger angle of incidence of the reference beam (R) (θr) is provided with a light shielding means for shielding the part so that the light beam diameter decreases in the reference light (R) (11).
