Notes on discs/files (continued)

Data hierarchy

DVD VIDEO/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/CD
A VCD/SVCD/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/
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
Group 1
Track 1 Track 2 Group 3 Group 4 Group 5
/File 1 /File 2
Up to 999 tracks/files
This system can recognize up to 4 000 tracks/files
on a disc. Also, the system can recognize up to
999 tracks/files per group and up to 99 groups on a
disc. Since 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/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-
standard 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.
