When
writing to a disc it is important to remember that there are a variety of
differnt discs
DVD+RW-
These discs are re-writable and have a capacity of 4.7 gb, these are usefull as
information can be added and removed from the disc allowing for multiple uses,
this is the main advantage over the DVD+R disc.
DVD-RW-
These disc are rewritable and have a capacity of 4.7 gb, this has the same
advantages as the +RW but with a higher writing speed. This disc with a dual layer was approved by the DVD
forum but the manufacturing didnt materialize due to cost.
DVD+R-
These discs can only be written on once which is useful for a film as the film
is permantly on the disc and cannot be removed, this also however means that if
an error occurs while burning the disc then the disc is ruined. These discs,
just like the DVD+RW, have a capacity of 4.7 gb
DVD-R-
These discs are very similar to the +R in terms of capacity and writability,
but where it surpasses the +R is with the production of a dual layer version,
this version has a capacity of 8.5 gb making it a far superior choice.
Dual Layer
Dual Layer is an upgraded disc that can hold up to 8.5 gb of data which is almost double the normal disc, this is because the disc has 2 layers which contain different pieces of information, a problem with this is that if a film is on both layers when the film switches to the second layer a visual blip can be seen for a brief period of time.
Writing Speed
The writing speed is the speed at which information is written to a disc, for example x1 will write 11mb of data to a disc per second, most of todays discs burn at x16. Some drivers offer a higher speed of writing, these transfer data much faster but can cause the information to become damaged over time.
Menus
This is the main way the viewer will navigate through the DVD features, these often contain screenshots from the film or things related to the film. These dvd menus can open in a variety of ways, some start with trailers and adverts related to the film
