In a storage system, sampled values of a function of four independent variables are converted from analogue to digital form to control light sources at positions selected by two of the variables to record the light positions on photographic means positioned by the other two variables, photo-electric read-out producing digital signals which are converted to analogue form. The variables are also obtained in digital form from analogue-to-digital converters to control the recording. |
