Abstract

PURPOSE:To record information efficiently, by providing a main index area, an additioal index area, a deleting and correcting index area, an information recording area and an additional information recording area, in the diameter direction of an optical disk. CONSTITUTION:In a main index area 32, indexes of a document such as flag + control field + track address + file number + comment are recorded. In an additional index area 33, in case when information has been recorded additionally in an additional information recording area 36, an index of its information is recorded. In a deleting and correcting index area 34, an index showing deletion or correction of recorded information is recorded. In an information recording area 35 and the additional information recording area 36, a document information of an index is recorded. In this way, an index is recorded efficiently.
