Do I need new equipment to play a recorded DVD+R
No. Completely in line with the philosophy of the DVD+RW
Alliance, the new DVD+R DL discs can be played on existing
equipment. This is because double layer playability has
been part of the DVD-Video/DVD-ROM standard since the beginning.
DVD+R DL compatibility is about equal to that of current
single layer DVD+R.
What products support DVD+R DL?
To record on a DVD+R DL disc, you need a DVD+R DL capable
writer. Refer to the DVD+R
DL Products listing for an overview of these new writers.
Do I need different media to record a DVD+R DL
Yes. To take advantage of the double layer recording capabilities
of the new DVD+R DL writers, you need the highly advanced
DVD+R DL media. This media consists of two recordable layers,
instead of just one (as with traditional recordable DVD
discs). Note that you can still record single layer DVD+R
discs and DVD+RW discs on those new DVD+R DL drives. The
release of DVD+R DL media has been announced by all major
blank media manufacturers, including Philips, Verbatim,
Optodisc, Ricoh, CMC Mr. Data, Maxell, Infodisc and Ritek.
Do I need new software to write a DVD+R DL disc?
To write a DVD+R DL disc, your CD/DVD recording software
needs to support DVD+R DL. Almost all software vendors have
announced support for DVD+R DL in their upcoming versions,
and most of them offer upgrades for their existing products
to include DVD+R DL writing support. Among the companies
that have already announced DVD+R DL support are Ahead Nero,
Sonic, Ulead, InterVideo, Roxio and Gear.
What is the capacity of a DVD+R DL disc?
A DVD+R DL disc hold 8.5 gigabytes of data. This is fully
equal to the amount of data on a pre-recorded double layer
DVD-Video disc, sometimes referred to as DVD9. A single
layer DVD holds 4.7 gigabytes. As the track distance on
both layers of any double layer DVD is about 10% wider,
the total capacity of both layers equals 8.5 GB.
How much video does a DVD+R DL disc hold?
As with DVD+RW and single layer DVD+R, the amount of video
one discs holds depends on the quality setting that was
chosen during recording. When recorded in the highest possible
DVD-Video quality, a DVD+R DL disc holds about 4 hours of
video. When video is recorded at VHS quality level, recording
time increases to up to 16 hours per disc.
Do I need to flip the DVD+R DL disc over to get
access to its full capacity?
No. Contrary to other recordable DVD proposals, where you
need to manually turn the disc over halfway through recording
or playback, a DVD+R DL disc nearly doubles the capacity
on a single recording side. The entire disc’s contents
can be accessed without the need to take the disc out to
turn it over. Furhtermore, a single sided disc allows for
easy identification on the label side.
Will single layer DVD+R continue to be available?
Yes. Because single layer DVD+R media holds up to 4.7 gigabyes
of data (equaling about 6 CD-Rs), this technology still
provides very high storage capacities suitable for a wide
range of applications. Furthermore, the new DVD+R DL writers
will still be able to record to single layer DVD+R as well
as DVD+RW media.
