ABSTRACT:
Data is recorded in holographic form on elongate film strips in a plurality of parallel, longitudinally extending hologram rows. The film is longitudinally moved past a light beam to reconstruct holographic patterns which are then sensed. The light beam is perpendicular to the film and movable transversely to the film so that any holograph row can be illuminated. The recorded holograms in a row can be searched for comparison with a reference number or symbol for credit card verification and the like in which a small subgroup of members, such as those who forfeited their credit, are to be identified. The reference numbers of the members of the subgroup are recorded on the film and a given member, that is the reference number of a given customer, is compared with the recorded holograms. The reference number of each member of the group is assigned to a particular row so that his number will appear in one and only one row of holograms on the film. Consequently, only one row needs to be scanned to determine the presence or absence of the given member in the subgroup.
