Currently the following types of DVD are available:
DVD-Audio: A high capacity audio medium.
DVD-R: DVD-Rs can store between 3.95, 4.7 and 9.4 GB of data. In order to
store 9.4 GB, you must use the second side of the DVD-R which means that
you have to turn it over.
DVD-RAM: This is a rewritable medium which can store either 2.6 GB (one
layer) or 5.2 GB (two layers) of data.
DVD-ROM: This is the data medium.
DVD-RW: This is a rewritable DVD which can be read by almost any standard
DVD-ROM drive or DVD player. DVD-RW drives can also read and write to
DVDs which are not rewritable. DVD-RWs have a storage capacity of 4.7 GB.
The difference between these and DVD-RAMs is that they can also be played
in standard DVD-ROM drives and standalone DVD players.
DVD+RW: This is a rewritable DVD which can be read by almost any standard
DVD-ROM drive or DVD player. DVD+RW drives can also read and write to
DVDs which are not rewritable. DVD+RWs have a storage capacity of 4.7 GB.
The difference between these and DVD-RAMs is that they can also be played
in standard DVD-ROM drives and standalone DVD players.
DVD-Video: DVD-Videos contain full-length feature films with high audio and
video quality. The videos are encoded in MPEG-2 format.
Additional information:
The UDF (Universal Disc Format) file system is used on DVDs. However the
data can also be accessed via an ISO9660 data system which is also included
on the DVD.
DVD format no longer corresponds to any of the formats specified in the
colored books.
El Torito
El Torito is a specification which describes the structure of a CD used to boot a
PC. A PC with a suitable BIOS can start the operating system from the CD and
therefore does not need a floppy disk or a hard disk.
Fast copying
This is a write process which does not involve storing the data to be written to the
CD on the hard disk first. The data is written directly onto the blank CD. Another
term used for fast copying is "on the fly".
Finalizing
Finalizing is similar to fixing, but applies to the entire disc. No additional data can
be written to a finalized disc. When you burn a CD or DVD in DAO mode, the disc
is automatically finalized. However, the data on a finalized CD-RW can still be
deleted (by choosing the Erase Rewritable item from the Recorder menu).
