摘要： A holographic memory reproduction apparatus which makes a wavelength of a reproducing laser beam coincident with a wavelength of a laser beam used for holographic recording when information is reproduced from a holographic recording medium. In the holographic memory reproduction apparatus 10, a temperature adjustment device 26 is attached to a semiconductor laser 12. On the holographic recording medium 16, wavelength information of the laser beam used for recording is recorded as a wavelength address hologram 28. When the information is reproduced, the temperature adjustment device 26 is controlled by a wavelength control device 24 in accordance with a signal beam from the wavelength address hologram 28, thereby making an oscillation peak wavelength of the semiconductor laser 12 coincident with the wavelength of the laser beam used for recording.

摘要： A holographic recording medium 10 is configured to have a recording layer 12 on which information can be recorded as holograms; and first and second heat generating layers 14A and 14B provided in a pair so as to sandwich the recording layer 12. Then, the first and second heat generating layers 14A and 14B are allowed to generate heat by being irradiated with a heat generating laser beam LB3 having a wavelength that is different from that of a signal beam LB1 or a reference beam LB2 for reproducing or recording information. The holographic recording medium and a method for recording and reproducing the same, and a recording and reproducing apparatus can compensate for shrinkage of the recording layer due to recording or variations in temperature, thereby allowing for reproduction of the holograms under optimum conditions.
