PURPOSE:To enable to accomplish record processing of data in a short time by making form setting of data block based on an index block each time when data are recorded in the data block. CONSTITUTION:Form setting is made to an index block IB having no data and adjoining first data block DB1 together with a block start mark BS. Data are set as recorded to the first data block DB1 and index of the data is set to the index block IB. After recording in the data block DB1, adjoining data block DB2 is set as a form together with a block start mark BS. Form setting is made similarly successively. Thus, data recording is made efficiently in a short time. |
