摘要： In case of reproducing a hologram recorded on an optical information recording medium, adjusting beam with the amplitude distribution and phase distribution at least partially the same as those of a signal beam upon recording is radiated to the optical information recording medium which records information. The diffracting beam diffracted by the hologram is detected by a photodetector. Based on the detected information, an incident angle of the reference beam to the optical information recording medium is appropriately controlled.

摘要： A position control method at high speed and high accuracy for recorded hologram is obtained. An optical information recording and reproducing device records an interference fringe obtained by interfering reference beam and signal beam as a hologram on an optical information recording medium and reproduces information using the reference beam from the hologram recorded on the optical information recording medium. The optical information recording and reproducing device includes: a detection light generation unit that generates light including a part of the signal beam as detection light; a detection light incident unit that causes the detection light to be incident on the recorded hologram; and a light detection unit that detects a light amount of diffracted beam by the detection light incident on the hologram. A position of the recorded hologram is detected based on an output of the light detection unit.

摘要： In recording and reproducing devices that use angular-multiplexing holography, accessing a recorded hologram of interest had taken time because after positioning at the vicinity of the hologram, it had been necessary to carry out fine adjustment of the position while checking the signal quality of the hologram. The optical information recording and reproducing device according to the present invention uses angular-multiplexing to record interference patterns formed from a signal beam and a reference beam onto an optical information recording medium as page data and reproduces information from the optical information recording medium, said optical information recording and reproducing unit being provided with: a light-source unit that outputs light; an optical splitting unit that splits the light into a reference beam and a signal beam; an angle controlling unit that controls the angle for the direction of angle multiplexing at which the reference beam enters the optical information recording medium; an optical detecting unit that detects a reproduced image that is reproduced by using the reference light; and a position control unit that controls the position relationship between the reference beam and the optical information recording medium. The device treats a set of page data as a book, and during recording, at least a portion of the page data in adjacent books is recorded while the entrance angle for the direction of angular-multiplexing for the reference light is shifted by means of the angle controlling unit. During reproduction, at least a portion of the light amount of a reproduced image is detected by using the optical detecting unit, and the position of the book is detected on the basis of information about the detected light amount.
