ABSTRACT:
Areas are hierarchically ensured as directories for data to be recorded in advance. Therefore directories and files are continuously arranged as much as possible on a disk, and the number of seeks during data read, which is conventionally large because other data is mixed in the same area, is decreased as few as possible. When the files and directories belonging to directory1(DIR1) and directory2(DIR2) are recorded on a disk and when the files and directories belonging to directory1(DIR1) are recorded in an area-ensuring mode, an area on a disk for the files and directories belonging to the directory1(DIR1) is ensured previously. The positions where lower-order Files1, 2and directories of the directory1(DIR1) are recorded in an area concerning the directory1(DIR1) as in the case of File1-1, File1-2, and File12. File3of the directory2(DIR2) is not recorded in continuous areas for the directory1(DIR1).
