摘要： A hologram recorder includes a signal beam irradiator to irradiate a signal beam, which is optically modulated in accordance with information to be recorded, to a recording medium at a predetermined incident angle. The hologram recorder also includes a recording prism provided with surfaces including an incident surface, a reflective surface and an emission surface for light so that a recording reference beam is guided to the recording medium by way of these surfaces. A pivot mechanism of the hologram recorder causes the recording prism to pivot above the recording medium for changing the incident angle of the recording reference beam at the recording medium, with the recording reference beam kept to overlap the signal beam.

A beam condensing spot of the on-axis beam and the off-axis beams is formed, with a predetermined diameter at a predetermined position on an optical axis on a way to the image points. At least one of the on-axis beam and the off-axis beams has a diameter, at the predetermined position on the optical axis, smaller than the predetermined diameter of the beam condensing spot.

摘要： A multiple hologram recorder includes an optical system and an incident angle controller. The optical system applies a recording beam and a reference beam to a unit recording region of a hologram recording medium. The recording beam is modulated in accordance with information to be recorded. The reference and the recording beams have the same wavelength. The angle controller adjusts the incident angle of the recording or reference beam to preset angles. Every time the incident angle is adjusted to one set angle, one-page holographic recording is performed. The set angles include a reference angle associated with an angular interval. The incident angle controller causes the incident angle to continuously vary within the angular interval when the incident angle is adjusted to the reference angle. This continuous variation is performed with the recording and the reference beams irradiating the unit recording region.
