About “System File”

The system file is space on the disc that is used to store information other than audio files; for instance,
track numbers.
If the MiniDisc were a book, the system file would correspond with the index or table of contents.
The recorder rewrites the system file whenever an operation such as recording, adding or deleting track
marks, or moving tracks has been done. (“SYSTEM FILE WRITING” appears in the display when the
recorder is rewriting the system file.) While the recorder is writing disc information, make sure not to
move or jog the recorder or disconnect the power source as this may cause the information to be
incorrectly recorded or the disc contents to be lost.
