    Abstract: PROBLEM TO BE SOLVED: To control a laser beam that irradiates a hologram recording medium in accordance with the energy value of the laser beam from a laser device. SOLUTION: A hologram device allows a coherent data beam corresponding to the data to be recorded and a coherent reference beam to enter a hologram recording medium and records the data as a hologram in the recording medium, wherein the device is equipped with a photodetection part to detect intensity of light in at least one of the data beam and the reference beam, a decision part to decide from the detected intensity of light whether or not the intensity of the data beam and the reference beam reaches a reference value capable of forming a hologram having predetermined diffraction efficiency, and an interruption part to interrupt incidence of at least one of the data beam and the reference beam when the decision part decides that the intensity of light reaches the reference value.
