<P>PROBLEM TO BE SOLVED: To provide a holographic recording medium which can considerably suppress influence of servo light on recording layer. <P>SOLUTION: In the holographic recording medium 1, a selective reflection film 12 which allows recording and reproduction light RW to pass and reflects servo light S of different wavelength from the recording and reproduction light RW is prepared closer to an incident side of light than a recording layer 14, and a first gap layer 13 which absorbs servo light S is formed between the selective reflection film 12 and the recording layer 14. <P>COPYRIGHT: (C)2008,JPO&INPIT |
