DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 8.54 GB (called DVD-9) and...

MP5120A, RW5120A, MP5125A, RW5125A, MP5163A, MP5240A, RW5240A, MP5308DA cannot write DVD +R DL media.

Yes, it seems to, it will be necessary to test more, but I have already tested a copy of my DVD #1 of "The Return of the King" (long version). Copied on DVD+R DL Verbatim Datalife Plus (Mitsubishi Kagaku Media) 2.4x, burned at 4x with Nero 6.6.0.3. I have ripped the tracks with DVDShrink without compression, keeping all items (menus, etc.) ... 7,45 Gb burned.

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.

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.

A dual layer DVD looks and feels just like a standard DVD. However, dual layer DVD??s allow the user to record two separate layers of data onto the same disc, meaning that it can store almost twice as much data as a typical DVD. A standard recordable DVD has a storage capacity of around 4.7GB, while a Duel Layer DVD will allow for around 8.5GB.

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.

A dual-layer disc has two layers of data, one of them semi-transparent so that the laser can focus through it and read the second layer. Since both layers are readable from the same side, a dual-layer disc can hold almost twice as much as a single-layer disc, for over 4 hours of video (see 3.3 for more details). Many dual-layer discs are currently available (such as Contact, Goldeneye, Species, Raging Bull, and Rain Man).

DVD-R is a "home made" DVD. That is, a movie that's been ported over from VHS, tweaked with a time-based corrector, and recorded onto a consumer-grade DVD. These generally look significantly better than the original VHS. However, be warned, that not all DVD players can handle DVD-R's. If you are unsure of your player's compatibility please visit http://www.vcdhelp.com/dvdplayers.php for a comprehensive list of most older DVD players and their model numbers.

The reflective layer is typically between 50 and 100 nanometers thick. The same is true for the dye-recording layer. The lacquer protective layer applied to all CD-R media is significantly thicker, usually in the range of 3 to 10 micrometers. Many CD-R manufacturers, including Kodak, apply an additional protective layer to improve resistance to handling damage or to allow thermal or inkjet printing. This layer can be 5 - 20 micrometers thick. For more information abut CD-R construction, see:

There are three recordable versions of DVD-ROM: DVD-R, DVD-RAM, and DVD-RW. DVD-R can record data once (sequentally only), while DVD-RAM and DVD-RW can be rewritten hundreds of thousands of times. Final versions of the DVD-R and DVD-RAM specifications were published in August 1997 (see 6.1). DVD-RW will be finalized by the end of 1998. These recordable media are not currently usable for home video recording (see 1.14), though home DVD-RAM recorders will eventually become available.

DVD+R is a newer format that offers special features for those recording movies. DVD-R is still used, and some drives will be able to read both formats. Most Macintosh DVD drives only support DVD-R media. Check with your drive manufacturer to see which types of discs will work in your drive. You can also visit DVDRhelp.com to check compatibility, or read more technical information about the format differences at DVDRhelp.com. All our discs are recorded using DVD-R media. [top]
