PURPOSE:To improve access efficiency by counting the number of calc control records in a file during reorganizing process and changing automatically the information of data base catalog as well. CONSTITUTION:A logical image record file 1 is developed on a memory by a logical image record input means 2. A page form editing device 3 makes reorganization by the number of calc control records per file calculated by using the number of calc controlling records per page and the number of pages (number of pages after expansion) as the information possessed by a data base catalog 7. A data base catalog changing means 4 changes the data base catalog by referring to one edited to page form (number of calc controlling records), and a page form output means 5 outputs one edited to page form to a data base film 6. Thus calc records are uniformly dispersed in the file and the access efficiency is improved.
