Tips on data storage media
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
Do not play single-CDs (80 mm) with an
adapter. Only use 12 cm diameter CDs.

If you insert thicker data carriers, e.g.
ones that have data on both sides (one

Data carriers which contain data on
both sides can cause playback prob-
lems because the storage layers are
thinner than one-sided data carriers.

CD-RW CDs.
Permissible file systems
The permitted file system is
ISO9660/Joliet for CD-R and CD-RW.
Multi session discs
With multi session discs, the content of the
first session determines how COMAND
treats the CD. For example, if the first session contains
data in audio CD format and the second
session contains data in MP3 format,
COMAND will treat the CD as a conven-
tional audio CD.
File structure
When creating an MP3 CD, you can orga-
nize MP3 tracks into folders. A folder can
also contain additional folders.
The root directory may have a maximum of
255 entries in total (folders or tracks).
A CD may have a maximum of 255 folders
in total. A maximum of 255 tracks are per-
missible per folder.
Mathematically a maximum of 65025
tracks would result. However, this amount
is usually not reached since MP3 requires
approx. 1 MB storage per minute recorded.

Tips on creating MP3 CDs
i
CDs, software and hardware for writing
audio data to CDs are widely available.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD.

Track names and folder names
When creating an MP3 CD, you can assign
names to the MP3 tracks and folders.
COMAND uses these names in MP3-mode
for the corresponding display.
Please note the following when assigning
track and folder names:
Per folder a maximum of 1800 charac-
ters are available for title and folder
names combined.
Exceeding this number, COMAND can-
not display all titles and folders.
Track and folder names must contain
at least 1 character.
Track names may contain up to fifty
characters. If a track name exceeds
this character limit, COMAND will not
be able to display it in full.
Track names must have the file exten-
sion “mp3”.
A period must appear between the
track name and the file extension.
Example of a correct track name:
Track1.mp3
Empty folders or folders containing data
other than MP3 tracks will not be dis-
played by COMAND.
If MP3 f iles are stored in the root direc tory
itself, the root directory also counts as a
folder. COMAND will then display the root
directory name as a folder name.
Permissible MP3 formats
COMAND supports the
MPEG1 Audio Layer 3 format.Permissible bit and scan rates
Fixed and variable bit rates up to
320 kbps
Scan rates from 24 kHz - 48 kHz
i
COMAND does not support ID3 tags.
Tips on creating MP3 tracks
i
In everyday speech, this format has
been replaced by the designation
“MP3”.
i
It is recommended to use MP3 tracks
with a bit rate of 128 kbps or higher
and with a scan rate of 44.1 kHz or
higher. Lower rates may impair quality.
This is particularly true if the Sound
function*
LOGIC7 Surround has been acti-
vated.
