Definitions

  • a recording medium for recording image data as element holograms with interference fringes generated by interference between an object beam representing the image data and a reference beam including a first element hologram formed by interference fringes generated by interference between an object beam representing first data and a first reference beam applied at a first angle, and a second element hologram formed by interference fringes generated by interference between an object beam representing second data and a second reference beam applied at a second angle which is different from the first angle, the second element hologram overlapping the first element hologram such that the first element hologram has a portion remaining unoverlapped by the second element hologram.
  • the hologram recording medium can have a certain large storage capacity and can easily be duplicated into a large number of copies
  • the reproducing apparatus can have a simple makeup and is able to reproduce recorded data stably.
  • the reproducing apparatus is suitable for use in a system wherein computer data and AV contents data are recorded in the hologram recording medium, such hologram recording mediums are widely distributed, and the general user acquires the data recorded in the hologram recording medium using the reproducing apparatus.
  • an element hologram 8 B is scanned at the time when the beam spot SPB of the reproducing reference beam L 4 B covers the element hologram 8 B in its entirety.
  • the beam spot SPB of the reproducing reference beam L 4 B has its center positioned near the center of the element hologram 8 B.
  • only the reference light source 7 B is turned on, and the reference light source 7 A is turned off.
  • the beam spot SPB generates a reproduced image of the element hologram 8 B, and the reproduced image is read by the imager 5 through the collimator lens 4 .
  • step F 103 If the differential signal (SA ⁇ SB) is of a negative value in step F 103 , i.e., during the period in which the differential signal (SA ⁇ SB) exceeds the negative threshold value th shown in FIG. 9D , the reference beam source 7 A is turned off as shown in FIG. 9E , and the hologram memory 3 is irradiated with only the reproducing reference beam L 4 B from the reference beam source 7 B during a period B shown in FIG. 9G . As can be seen from FIGS.
