    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.
