1.6.2. Blu-ray, DVD, and CD Media Format
Definitions
Blu-ray Disc Recordable - BD-R (Single or dual layer)
✦ Recorded once.
✦ Cannot be accidentally erased.
✦ Ideal format for archiving valuable data or storing and distrib-
uting video material.
Blu-ray Disc Rewritable - BD-RE (Single or dual layer)
✦ Capable of rerecording or rewriting. Good quality Blu-ray
discs can be overwritten approximately 10,000 times.
✦ Extensive editing functionality on the disc.
✦ Ideal format for making sequential backups or recording vid-
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.
1.6.3. For Best Recording Results:
✦ Close all other open programs and disconnect from the in-
ternet
✦ Copy data to your hard drive first
✦ Check media speed rating
✦ Use media that is free of scratches and fingerprints
