Title: File updating/adding method and file access method for cd-rom medium
Inventor: ARAI YOSHIO
IPC: G06F12/00
Filed: 1989-04-07
Abstract: PURPOSE:To decrease the number of processes by writing a file itself into an unused area of a CD-ROM medium when the file contents are updated or at addition of files and at the same time writing a subdirectory into the final logic sector of the CD-ROM medium. CONSTITUTION:The presence or absence of an unused area of a CD-ROM medium is decided and then the presence or absence of a rewritten CD-ROM medium is decided by reference of the final logic sector of the CD-ROM medium. Then a subdirectory (SD2') 7 including a directory code showing the recorded information on the files (B', E) 6 is written into the final logic sector of the CD-ROM medium for identification of the update of the file contents and the addition of files when the file contents are updated or at addition of files. At the same time, the file itself is written into the unused area of the CD-ROM medium. Thus the update of the file contents or the addition of files is carried out just once within a range shown by a directory. Then the time and labor and the cost required for revision are reduced.
