This paper will present the characteristics of recording medium as well as the principle and features of recording, duplicating, displaying, copying, searching and other functions of the practical HUFS system. The medium is a silver halide emulsion with special proper-ties. Its resolution is up to 5,000 1p/mm and the first order diffraction efficiency of the unbleached emulsion is about 40-50% etc.. We can get the extremely bright daylight reflective holograms photographed and record more than 3,000 holographic points in a single ultrafiche with a size of 4"x6" which can store 3,060-12,240 pages of magazines in sexto-decimo. The reflective holograms and the ultrafiches can be preserved almost forever. This emulsion can be preserved for half to one year at the room temperature.
