Notes on discs/files (continued)

Data hierarchy

DVD VIDEO and DVD VR
A DVD VIDEO consists of "titles" and each title
may be divided into "chapters".
A DVD VR consists of "original programs" or "play
lists" and each original program/play list may be
divided into "chapters".
Title 1/Original program 1/
Play list 1
Chapter 1 Chapter 2 Chapter 3 Chapter 1 Chapter 2
VCD, SVCD and CD
A VCD, SVCD or CD consists of "tracks".
In general, each track has its own track number.
(On some discs, each track may also be further
divided by indexes.)
Track 1 Track 2 Track 3
MP3, WMA, WAV, JPEG, ASF, DivX, MPEG1 and
MPEG2 files
Audio, still pictures and video are recorded as
tracks/files on a disc or a USB device. Tracks/files
are usually grouped into a folder. Folders can also
include other folders, creating hierarchical folder
layers.
This system simplifies the hierarchical construction
of files and manages folders by "groups".

Up to 99 groups

Up to 999 tracks/files
This system can recognize up to 4000 tracks/files
on a disc and a USB device connected to the
[USB1 VIDEO/AUDIO PLAY] terminal, and up to
2000 tracks/files on a USB device connected to
the [USB2 AUDIO/REC PLAY] terminal. Also, the
system can recognize up to 999 tracks/files per
group and up to 99 groups on a disc and a USB
device connected to the [USB1 VIDEO/AUDIO
PLAY] terminal, and up to 999 groups on a USB
device connected to the [USB2 AUDIO/REC
PLAY] terminal. Because the system ignores the
tracks/files with numbers exceeding 999 and the
groups with numbers exceeding 99, these cannot
be played back.
If there are any type of files other than MP3, WMA,
WAV, JPEG, ASF, DivX, MPEG1 or MPEG2 files
on a disc, those files are also counted in the total
number of files.

Handling discs

• Do not use a commercially-available non-stan-
dard shape disc (like a heart, flower or credit
card, etc.), because it may damage the system.
• Do not use a disc with tape, stickers, or paste on
it, because it may damage the system.
• Do not bend the disc.

Cleaning discs
Signal surface
Wipe the disc from the center outward with a soft
cloth.
• Scratches concentrated on a certain part cause
sound dropout.
• Be sure not to use thinners, benzenes, cleaners
for analog records, or other chemical agents.
