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.

摘要： A disk-type hologram recording medium and a hologram recording and reproduction device utilizing such a recording medium are provided. The hologram recording and reproduction device includes a spatial optical modulator provided with a plurality of optical elements arranged in a grid-like form. These optical elements are divided into groups each associated with 1 bit of data for performing required light modulation. Thus, a special pattern exhibiting a greater S/N margin for 1 bit can be recorded in the recoding medium. During data recording or data reproduction, the special pattern is read from the recording medium, and based on the retrieved special pattern, fine adjustment by servo control is conducted for adjustment of tilting or focusing of the recording medium and for adjustment of the wavelength of the light emitted from the light source.
