<p>A hologram device records/reproduces information on/from a recording medium (3) having holograms (4) thereon by irradiating light beams emitted from a light source (1) thereon. The light source (1) is composed of a substrate (10) and a plurality of light emitting units (11a,11b,11c) arranged on the substrate. A condensing unit (2) is provided between the light source and the recording medium (3) to condense a plurality of light beams (L0a,L0b,L0c) emitted from the plurality of light emitting units onto approximately the same location (4) of the recording medium.</p> |
