摘要： Disclosed is a holographic recording medium and methods of manufacturing the holographic recording medium. The example of the medium has a recording layer containing a three dimensionally cross-linked polymer matrix including an epoxy resin, a radically polymerizable monomer, and a photo radical polymerization initiator. The radically polymerizable monomer comprises both N-vinylcarbazole (VC) and N-vinylpyrrolidone (VP) or N-vinylcarbazole alone. The weight ratio of N-vinylcarbazole (VC) to the sum of N-vinylcarbazole (VC) and N-vinylpyrrolidone (VP), i.e., (VC/(VC+VP)), is not smaller than 0.75 and not larger than 1.0.

摘要： A method for storing holographic data in a medium having a reflection layer and a recording layer comprises: recording, rotating and repeating. An interference pattern is recorded at a recording position of the recording layer of the medium in a stationary state. The interference pattern is formed by an interference between an object beam and a reference beam which are irradiated into the recording layer from an opposite side of the reflection layer. The medium is rotated so as to shift the recording position by a distance of n×Sh where n is a positive integer and Sh is a predetermined recording shift amount. The recording and the rotating are repeated alternately.

摘要： Provided is a technique for reproducing information recorded on a holographic recording medium including a reflecting layer and a recording layer. When reproducing, a reproducing reference light is focused on a reflecting surface of the reflecting layer to produce a phase conjugate reproduced light and an ordinary reproduced light, and the phase conjugate reproduced light and the ordinary reproduced light are guided to a sensing surface of an image sensor to produce on the sensing surface a first reproduced image and a second reproduced image smaller than the first reproduced image, respectively. An intensity of the ordinary reproduced light on the sensing surface is higher than an intensity of the phase conjugate reproduced light on the sensing surface. An output of the image sensor corresponding to a non-overlapping portion of the first reproduced image which does not overlap the second reproduced image is utilized for reproducing the information.
