Abstract

PURPOSE:To efficiently access secondary information for control and to flexibly apply the information to various retrieving systems by dividing the storing area of a data file and the storing area of the secondary information for control. CONSTITUTION:The storing area of an optical disk is divided into two areas, namely, into a data area AD to store the data file and a controlling information area AM to store controlling information to execute the access of the data file. Further, the controlling information area AM is divided into a header area HD, a system area SM and a data area KY for retrieval. Thus, the storing area of the data file and the storing area of secondary information for control are divided and the access can be independently executed to the respective areas. Then, the secondary information for control can be secured with an arbitrary size of the unit of sectors of the optical disk in a successive area and the access can be executed to the secondary information for control at a high speed. Thus, a file control system can operate a file and retrieving information with the separated system.
