Method for producing a duplicate hologram recording medium, apparatus for producing a duplication master, apparatus for producing a duplicate hologram recording medium, and duplication master

摘要

An apparatus for producing a duplicate hologram recording medium includes: a positioning section configured to place the duplication master and the duplicate hologram recording medium at predetermined relative positions; an angle selective plate arranged between the duplication master and the duplicate hologram recording medium, the angle selective plate having an angle selective film whose transmittance changes in accordance with an incidence angle of a light beam; and a duplicating-reference-beam generating and radiating section generating a duplicating reference beam, and radiating the duplicating reference beam at such an incidence angle that the duplicating reference beam is transmitted through a predetermined region of a recording layer of the duplication master and is reflected by the angle selective film.
