Definitions
Blu-ray Disc Recordable - BD-R (Single or dual layer)
✦

✦
Cannot be accidentally erased.
✦
Ideal format for archiving valuable data or storing and distrib-
uting video material.

eo for time shifting purposes.
Blu-ray Disc Read Only Memory - BD-ROM
✦
Contains pre-recorded data.
✦
Although a BD-ROM may contain any form of data, most are
HD movies for playback on Blu-ray Disc players.
✦
BD-ROM can be read on your computer using the LaCie Slim
Blu-ray drive provided you own the appropriate playback
software, compatible system, graphic card, and monitor (see
1.2.2. Video and High Definition (HD) Playback
).
Blu-ray Disc Recordable Low to High - BD-R LTH
✦
A write-once format that supports less expensive Blu-ray discs
with an organic dye recording layer.
✦
Many existing Blu-ray burners are compatible with this new
format and no further investment in new technology is neces-
sary.
DVD+RW Discs
✦
Best suited for: backing up and archiving digital content.
✦
These discs are functionally similar to CD-RW and DVD-RW
discs, but record in the same way as DVD+R. Using Direct
Overwrite (DOW) recording, this type of disc allows new data
to be written directly over existing data in a single pass.
DVD-RW Discs
✦
Best suited for: backing up and archiving digital content.
✦
These discs serve the same general purpose as CD-RW me-
dia, but with 4.7GB of space versus 650MB.
✦
Discs can be written and erased up to 1,000 times.
DVD+R Discs
✦
Best suited for: recording DVD videos, storing multiple photo
albums, and data storage under 4.7GB.
✦
Just as CD-R discs, DVD+R is write-once, but with 4.7GB of
capacity versus 700MB for CD-R discs.
✦
DVD+R supports “lossless linking” and the combination of
Constant Angular Velocity (CAV) and Constant Linear Velocity
(CLV) recording.
DVD-R Discs
✦
Best suited for: recording DVD videos, storing multiple photo
albums, and data storage under 4.7GB.
✦
These discs are also functionally similar to CD-R media and
have the same capacity as DVD+R discs.
✦
There are two types of DVD-R discs: DVD-R General, which is
intended for home applications, and DVD-R Authoring, which
is intended for professional DVD-Video development applica-
tions.
DVD+RDL or DVD-RDL (Double Layer) Discs
✦
Ideal for: recording high-quality DVD videos, backing up, and
archiving large data DVDs.
✦
These discs follow the DVD+ recording techniques, but with
8.5GB of capacity versus 4.7GB for DVD±R discs.
✦
Larger disk capacity makes it possible to increase the video bit
rate for higher quality DVD videos.
DVD-RAM
✦
Best suited for camcorders and set-top boxes, as well as many
other situations where rewriting data is important.
✦
Considered a very reliable format thanks to its built-in error
control and defect management system.
CD-R Discs
✦
Best suited for: recording audio CDs and storing files, such as
photos or important documents.
✦
Files can not be deleted from CD-R discs, and you cannot
write over existing files on a CD-R disc.
CD-RW Discs
✦
Best suited for: exchanging files up to 650MB.
✦
Discs can be reformatted up to 1,000 times, and files can be
written over.
✦
Most CD-ROM drives and audio CD players cannot read CD-
RW discs.
