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.
