COMAND audio CD/audio DVD/MP3
Multisession CDs
For multisession CDs, the first session
type of the CD determines how COMAND
will process the CD.
For example, if the first session type is ac-
cording to the audio CD standard and the
second session type is according to the
data CD standard containing MP3 tracks,
COMAND will treat the CD as a conven-
tional audio CD. This means that it is only
possible to access the audio CD tracks.
Access to the MP3 tracks is not possible.
Similarly, if the first session type is accord-
ing to the data CD standard containing
MP3 tracks and the second session type is
according to the audio CD standard,
COMAND will treat the CD as a data CD.
This means that it is only possible to ac-
cess the MP3 tracks. Access to the audio
CD tracks is not possible.
File structure on a disc
When you create an MP3 disc, the MP3
tracks can be organized in folders. A folder
can also contain other folders. A disc can
contain a maximum of 255 folders. Each
folder can contain a maximum of
255 tracks and 255 folders. A disc can
contain a maximum of 4 000 tracks. Usual-
ly this number will not be reached because
each minute of an MP3 track requires ap-
proximately 1 MB of storage space.
Track and folder names
When you create an MP3 disc, you can as-
sign names to the MP3 tracks and folders.
COMAND uses these names for the corre-
sponding display in MP3 mode. Empty fold-
ers or folders which contain data other
than MP3 tracks are not displayed by
COMAND.
If MP3 files are saved in the root directory
itself (uppermost directory on storage me-
dium), the root directory will also be treat-
ed as a folder. COMAND will then show the
name of the root directory as the folder
name.
You must observe the following when as-
signing track names:
앫
Track names must have at least one
character.
앫
Track names must have the extension
“mp3”.
앫
There must be a period between the
track name and the extension.
Example of a correct track name:
Track1.mp3

COMAND does not support ID3 tags.
