Abstract
PURPOSE:To quickly find out purposed information, by registering a storing condition to a file header in the order of record and storing this file header to a store control information as storage control information. CONSTITUTION:The data file is composed of plural variable length records and the storing condition in the data area of the respective variable length records to constitute the data file is registered to the file header in the order of record. Then, this file header is used as the storage control information. Thus, a data access can be executed in the unit of data files and a time to search data, which are purpose, can be shortened. Since the storage control information are formed for the unit of data files, the information quantity can be suppressed and the utilizing efficiency of the optical disk can be improved.
