File Structure of Discs
DVD VIDEO
Typically, DVD VIDEO discs are made up of larger units called
“titles”. Each title has a number (title number) that can be used
to select desired titles. Titles are further divided into units called
“chapters”. 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 (a single
chapter). However, chapter marks are automatically inserted
when recording is paused, or audio changes from monaural or
bilingual to stereo due to commercial breaks, etc. It is also
possible to insert chapter marks at desired locations during
playback. (

When you record a programme on a DVD-R/RW (Video mode)
disc
A single recording session results in a single title (a single
chapter). However, chapter marks are automatically inserted
when recording is paused, or audio changes due to commercial
breaks, etc. It is also possible to insert chapter marks at desired
locations during either recording or playback. Once the disc has
been finalised, these chapter marks are deleted and new chapter
marks are assigned automatically approximately every 5
minutes.
●
In Video mode, even before finalising, it is impossible to
perform editing operations other than changing the disc name
and/or title names and deleting programmes and/or titles.
●
After finalising, it is impossible to perform editing operations.
Audio CD/Video CD
Typically, Audio CD discs are divided into separate tracks each
containing one song. Each track is assigned a number. For
example, the third track is Track 3. The same is true for Video CD
discs.
However, some discs are not divided into tracks.
