The TRITON STUDIO can use packet writing to write to a
CD-R/RW.
After formatting the media, you can use it in the same way
as a floppy disk or hard disk.
■ About packet writing
Packet writing is a method of dividing data into small units
called “packets” so that the data can be written efficiently,
and is suitable for adding or updating data.
As its packet writing format, the TRITON STUDIO uses
UDF (Universal Disk Format), the format that is also used
on DVD discs. This means that formatted CD-R/RW media
can also be read by packet writing software that supports
UDF.
The TRITON STUDIO supports UDF version 1.5.
■ Usable media
To save data, please use media that has been formatted
by the TRITON STUDIO.
• 650 MB and 700 MB CD-R media that supports up to 16×
writing
• 650 MB and 700 MB CD-RW media that supports up to
4×/10× writing
■ Formatting
In the same way as when formatting a floppy disk, insert
blank or previously-formatted media into the drive, and
execute the page menu command “Format” (Disk Utility 0–
3F).
When writing to the CDRW-1 option, do not subject the
TRITON STUDIO to vibration or physical shock, since
this may cause errors.
Cautions when formatting
[1] For a CD-R
• Data that has been written to CD-R cannot be erased as it
can on a floppy disk. This means that re-formatting
previously-formatted media will not increase the free
area. (Approximately 20 MB of space will be used to add
a new session.)
• Only Quick Format can be selected.
Quick Format requires less than a minute to execute.
It is not necessary to apply Full Format to CD-R media.
[2] For a CD-RW
• In the same way as a floppy disk, a CD-RW can be
formatted to erase the previously-written contents. This
means that re-formatting the disc will increase the free
area.
• Quick Format: Select this if the media has already been
formatted in UDF format.
Full Format: Select this if the media is blank or if it has
not been formatted in UDF format.
You should also execute this type of formatting if fre-
quent writing errors occur when writing to the media.
The time required for formatting will be approximately 2
minutes for Quick Format, and approximately 50 min-
utes for Full Format.
• After formatting, the usable area for 650 MB/700 MB
media will be approximately 530 MB/570 MB
respectively
■ Cautions when using packet writing
[1] For a CD-R
• Deleting a file merely makes the file appear as if it had
been deleted, and will not increase the free area. Also,
each time a file is updated, a new file is added, and
processing is performed to make it appear as though the
file had been overwritten.
[2] For a CD-RW
• In the same way as on a floppy disk, deleting a file will
increase the free area. Also, updating a file will
overwrite the file over the previous location.
[3] About writing data
• Using packet writing to save data on a CD-R/RW will
take a longer time because writing to CD-R/RW is
slower than writing to hard disk. The time will also
depend on the CD-R/RW drive you use, and on the
writing speed supported by the media you use.
■ Loading into an external device
other than the TRITON STUDIO
[1] For a CD-R
• The disc can be read by a computer on which packet
writing software is installed.
• By converting it into ISO9660 format, you can make it
possible for the data to be read by an external MIDI
device that supports ISO9660 format, or by a computer
on which packet writing software has not been installed.
For details on the conversion, refer to page menu
command “Convert to ISO9660 Format” (Disk Utility 0–
3G).
[2] For a CD-RW
• The disc can be read by a computer on which UDF
reader or packet writing software has been installed.
• This disc cannot be converted into ISO9660 format, and
therefore cannot be read by external MIDI devices that
support ISO9660 format.
Since the conversion to ISO9660 format adds ISO9660
session data, it consumes approximately 20 MB of space.
External MIDI devices that support ISO9660 format (*1)
(manufactured by Korg Corporation)
• TRITON/TRITON pro/TRITON proX/TRITON-Rack (*2)
• D1600/D12/D16
* As of February 2002
*1: Supports ISO9660 level 1.
*2: Only the first session can be read.
If reading on an external device other than the TRITON Studio
When you copy a file larger than 1.9 Mbytes from CD-
R/RW (or other media with a slow access speed) to CD-
R, the file may not be copied in a continuous state.
