    Abstract: System for recording graphical data in the form of holograms on a plurality of hologram carriers, each hologram carrier storing a group of holograms, and for reading selected ones of these graphical data. The recording means includes an object carrier for holding transparent objects, a coherent light spurce giving rise to an object beam passing through an object and a recording reference beam describing a cone around the axis of the object beam and able to take discrete azimuthal angular positions on the cone. The reading means includes a coherent light source giving rise to a reading reference beam describing a cone around the normal to the hologram carrier and able to take discrete azimuthal angular positions on the cone. The hologram carriers are arranged in a matricial array and a given hologram has three addresses: the coordinates of the hologram carrier which contains it and an angle which is the position of the reading reference beam on the cone which it describes.
