ABSTRACT:
The method and apparatus for storing the data base of gridded type data on a plurality of rotary type data memory devices such that data update to a utilization system, e.g., a computer generated imagery (CGI) processor may be more effectively implemented. For the generalized case of N rotary data memory devices and for a data base of gridded type data which may be represented by rows and columns of data elements, data elements of each row are "mapped" to the memory devices in accordance with a repetitive and cyclical pattern. For example, for each row of the grid, the data for each data element of N successive elements is stored on a different one of the N rotary data memory devices and for successive groups of N elements the data is similarly stored in accordance with a repetitive, cyclical pattern wherein each cycle of the pattern includes N successive elements, the data for each of which is stored on a different one of said rotary data memory devices.
