Abstract

PURPOSE:To add, correct and delete a record, by using a file storage device such as an optical disk which is not rewritten, etc. in a data part. CONSTITUTION:In a keyword part 40, an index word required for retrieving a record is stored, and in an array part 41, an address corresponding to both each keyword and the record number of a map part 42 is stored. The record is divided into plural element pieces, and an element piece which is corrected most frequently is called a special element piece and other element pieces are called a general element piece. In the map part 42, a special element piece (a) corresponding to each record, and an element piece in a data part of a general element piece are stored. In the data part 43, the general element piece is stored continuously without leaving a space from the head of the data part, which is made to a working area. The part at and after the working area is set to an unused area.
