Recording Medium and Format	File Structure of Discs

DVD-RAM

●Recording and erasing can be performed as many times as possible on a disc.

●Editing can be performed after recording, such as deleting unwanted parts.

●While recording, it is possible not only to start playback of a programme currently being recorded, but also to watch another programme previously recorded.

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.

DVD-RW (VR mode)

●Recording and erasing can be performed as many times as possible on a disc.

●Editing can be performed after recording, such as deleting unwanted parts.

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. ( pg. 34)

DVD-RW (Video mode)

●Can be played back on other DVD players.

●New recording can be performed by erasing all the data on a disc once played back.

DVD-R

●Can be played back on other DVD players.

●Suitable when keeping a recorded disc for a long time.

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.

However, some discs are not divided into tracks.
