<p>A hologram recording device (A1) is comprised of a hologram recording means (1-8) for irradiating information light (I) and reference light (R) to every unit recording portion (T) of a hologram recording medium (100) to record a hologram, a bleaching light irradiating means (10, 11) for irradiating a bleaching light (B) to the hologram recording medium (100) to make the hologram recorded on the unit recording portion (T) optically stabilized. The hologram recording device (A1) is provided with a reading-out means (50) for reading a unit irradiating zone (S) of the bleaching light (B) from the hologram recording medium (10, 11) and an irradiating control means (40) for controlling the bleaching light irradiating means (10, 11) to irradiate the bleaching light (B) to every unit irradiating zone (S) in accordance with the information obtained by the reading-out means (50).</p> |
