Disc structure

DVD VIDEO/DVD VRA DVD VIDEO consists of “titles” and each title may be divided into “chapters”.

MP3/WMA/JPEG/ASF/DivX/MPEG1/MPEG2 discs

On an MP3/WMA/JPEG/ASF/DivX/MPEG1/ MPEG2 disc, each still picture (material) is recorded as a track/file. 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 a disc and manages folders by “groups”.

This system can recognize up to 4 000 tracks/files in a disc. Also, the system can recognize up to 150 tracks/files per group and up to 99 groups in a disc. Since the system ignores tracks/files with numbers exceeding 150 and groups with numbers exceeding 99, these cannot be played back.

•If there is any type of files other than MP3/WMA/ JPEG/ASF/DivX/MPEG1/MPEG2 files in a folder, those files are also counted in the total file number.
