<p>PURPOSE:To guarantee the same operations as those at the time of writing when an implemented file is read out so as to improve the reliability of data, by storing the number of skips at a faulty point in the previous file data as information when an abnormal state is detected. CONSTITUTION:When a normal state is confirmed by performing writing and collation with reread data, a normal file constitution 11 is established and, when an abnormal state is detected and, even when operations are repeated for a specific times, the abnormal state is not restored, another file constitution (containing skip blocks) 12 is realized. In order to store a skip state in the file 12, a back space process is performed to the previous writing block and the information of file reading skip times is written as the previous inside-block information. Thereafter, skipping is performed to the leading edge of the next writing block. Read data at the time of reading out an printing formats converting processes are surely skip-processed and the same operations as those at the time of implementation are made. Accordingly file data are guaranteed.</p> |
