    摘要： The invention relates to a method for writing holographic pixels in a holographic recordable film (3), comprising a photo component that can be changed photochemically and/or photophysically by exposure, wherein the holographic recordable film (3) is positioned above a reflection master (4), wherein a primary light beam (P) is directed at the holographic recordable film (3), wherein the primary light beam (P) penetrates the holographic recordable film (3) and is reflected by the reflection master (4) to form a reflection light beam (R). The primary light beam (P) and the reflection light beam (R) interfere in the holographic recordable film (3) within an interference zone (10) and change the photo component in the interference zone to form the holographic pixel. The method is characterized in that a transmission hologram (6) is arranged between the holographic recordable film (3) and the reflection master (4) and that the transmission hologram (6) diffracts the primary light beam (P) and/or the reflection light beam (R) with the proviso that the interference zone (10) has a larger lateral surface area, in relation to the directions orthogonal to the surface normal for the holographic recordable film (3), than in the absence of the transmission hologram (6).

    摘要： The hologram recording device and the hologram recording method for recording the data stored in the master recording body on the recording medium in the form of the hologram allow the use of the compact light source and reduce the power consumption. A recording medium 20 is stacked on a master recording body 10, to which reference beams 35 are applied each at an incident angle of θ1. The interference between diffracted beams 36 diffracted in the data storage sections 11a, 11b,... of the master recording body 10 and the reference beams 35 in the recording medium 20 occurs such that the data are transferred to the recording medium 20. The use of plural compact light sources for emitting the reference beams 35 allows the recording device to be compact while reducing the power consumption.

    摘要： The present invention provides a method of producing hologram tapes corresponding to a large number of prepaid cards having different characteristic codes from one another, using one hologram master plate.
    Hologram tapes are produced in the following manner. Namely, an elongate flat image expressing a random number in the form of a bar code is prepared. A hologram master is prepared based on the prepared flat image, and the prepared hologram master is wound around the surface of a drum 110. The etching technique is applied, to prepare a drum-shaped hologram master plate 101 formed with micro relief corresponding to interference fringes on the surface of the drum 110. By rotating the drum-shaped hologram master plate 101 on the surface of a long material sheet 120, the micro relief hologram master 111 on the surface of the drum-shaped hologram master plate 101 is repeatedly transferred onto the material sheet 120. Then, the material sheet 120 to which the micro relief hologram master 111 has been transferred is cut into hologram tapes each having a specific length.
