files stored in each directory.
When required, the following operation tables distinguish
reading and writing from partial reading and writing.

the file.
Partial read: Read only a part of the data in the file.
Write: Write data sequentially from the start to the end of
the file.
Partial write: Write data to a part of the file only.
Operations other than Read and Partial read are possible
only when the Write Inhibit tab of the disc is set to
recording enabled.
