<P>PROBLEM TO BE SOLVED: To provide a hologram recording medium in which a sealing portion of high reliability is easily and inexpensively provided on a recording layer in the outer rim of a hologram recording medium and to provide a method for manufacturing the medium. <P>SOLUTION: The method for manufacturing a hologram recording medium includes a step of forming a sealing portion by forming a recording layer 2 comprising a photosetting organic material that contains monomers, a hardening initiator and a sensitized dye on a transparent substrate 1, exposing the recording layer corresponding to the outer rim of the hologram recording medium to light L<SB>E</SB>at a photosensitive wavelength to harden the photosetting organic material so as to seal the photosetting organic material in a region inside the outer rim. The step of forming the sealing portion is carried out by exposing the recording layer while measuring the transmittance for the exposure light L<SB>E</SB>in the recording layer and then terminating the exposure when the transmittance measured reaches the transmittance or more corresponding to the end point of the hardening reaction of the photosetting organic material. <P>COPYRIGHT: (C)2007,JPO&INPIT |
