Abstract: To provide a user authentication information recording medium providing a unique hologram tape. [MEANS FOR SOLVING PROBLEMS] A long flat image 310 that expresses a random number in a rectilinear state in a form of a bar code is created, and hologram original image 42 of the random number of the form of a bar code is created based on this. Hologram original image 42 is coiled around surface of drum 100 so as to create drum-shaped hologram master 10D in which the small convexes/concaves corresponding to interference fringes is formed on the surface of drum 100. Rotating drum-shaped hologram master 10D on surface of long material sheet 20S so that small convexes/concaves hologram original image 110 of surface of drum-shaped hologram master 10D is transferred on material sheet 20S repeatedly; material sheet 20S is cut out into hologram tape T providing small convexes/concaves hologram original image 110 transferred.
