<p>Provided are a hologram recording device and a hologram reproducing device which can reduce data loss in holographic memory without specially processing an optical element. A hologram recording/reproducing device (1) is provided with an information generating section (3), which has, on the peripheral section, a unit encoded block of encoded recording target information inputted from an external device (4), generates page data having redundancy information which corresponds to the unit encoded block at the center section, and stores the generated page data in buffer memory (10); a control section (11), which receives signals from the external device (4), reads out the page data stored in the buffer memory (10) and makes a recording/reproducing section (12) drive; and a recording/reproducing section (12) which generates a signal light provided by modulating laser light by a pattern which corresponds to the page data stored in the buffer memory (10), based on an instruction given from a control section (11).</p> |
