File Structure Of Discs

DVD VIDEO
Typically, DVD VIDEO discs are made up of larger units called
AtitlesB. Each title has a number (title number) that can be used to
select desired titles. Titles are further divided into units called
AchaptersB. Each chapter has a number (chapter number) that can
also be used to select desired chapters. Note that some discs are
not divided into titles and chapters.
When you record a programme on a DVD-RAM/RW (VR mode)
disc
A single recording session results in a single title. In addition,
chapter marks are automatically inserted when recording is
paused. It is also possible to insert chapter marks at desired
locations during playback. (A pg. 26)
When you record a programme on a DVD-R/RW (Video mode)
disc
A single recording session results in a single title. In addition,
chapter marks are automatically inserted when recording is
paused. It is possible to insert chapter marks at desired locations
during playback. Once the disc has been finalised, these chapter
marks are deleted and new chapter marks are assigned
automatically approximately every 5 minutes.

This unit can recognise up to 9 hierarchies including directories
and files.
Also, it can recognise up to 250 files in each group, and up to
99 groups on a disc.
NOTES:

Video CD/SVCD discs that support Playback Control (PBC)
The contents of a disc are recorded into several hierarchies, and
played back according to the instructions on the screen while
navigating through the hierarchies. It is also possible to playback
recorded tracks consecutively without activating the PBC function
even when playing a PBC-compatible disc. (A pg. 27)
●
Regarding the contents recorded on discs
Some files may not be played back depending on the file types
and other factors.
