Controls in detail Audio system Multisession CDs For multisession CDs, the first session type of the CD determines how the audio system will process the CD. For example, if the first session type is according to the audio CD standard and the second session type is according to the data CD standard containing MP3/WMA tracks, the audio system will treat the CD as a conventional audio CD. This means that it is only possible to access the audio CD tracks. Access to the MP3/WMA tracks is not possible. Similarly, if the first session type is according to the data CD standard containing MP3/ WMA tracks and the second session type is according to the audio CD standard, the audio system will treat the CD as a data CD. This means that it is only possible to access the MP3/WMA tracks. Access to the audio CD tracks is not possible. File structure on a disc When you create an MP3/WMA disc, the MP3/WMA 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 data medium may contain a maximum of 500 tracks. Track and folder names When you create an MP3/WMA disc, you can assign names to the MP3/WMA tracks and folders. The audio system uses these names for the corresponding display in MP3 mode. Empty folders or folders which contain data other than MP3/WMA tracks are not displayed by the audio system. If MP3/WMA files are saved in the root directory itself (uppermost directory on storage medium), the root directory will also be treated as a folder. The audio system will then show the name of the root directory as the folder name. You must observe the following when assigning track names: RTrack The audio system is unable to recognize an MP3/WMA track if: Rthere Rthere is no period between the track title and the extension is no extension i The audio system does not support ID3 tags. Compatible file systems and compression methods The following compression methods are compatible: RMP3 RWMA names must have at least one char- acter.
