DVD+RW alliance announces dual layer DVD recordables

Liggy and Sviox used our news submit to tell us that that a new development in the DVD recordable area has been announced by the DVD+RW Alliance. This might bring the current DVD format war in a totally different perspective. The new dual layer technology will make it possible that a whopping 8.5 GB of data can be stored on the discs while remaining compatible with current DVD players. Philips has developed this technology in cooperation with Mitsubishi Kagaku Media, better known by their Verbatim brand and has put a lot of effort in the compatibilty of the media which is still an issue in the current DVD-RW vs DVD+RW format war.

border=0>Compatibility has been achieved through the use of a thin silver-alloy as reflector material in the upper layer giving a reflectivity from the layer of at least 18% in compliance with the dual-layer DVD-ROM standard. In addition, the transmission of the upper recording layer is greater than 50% to allow for read-out and recording of the lower recording layer. This layer has high power sensitivity since the upper layer absorbs and reflects part of the incoming light. It also has a much higher reflectivity (> 50%) which after double transmission through the upper layer also results in an apparent layer reflectivity (at the disc surface) of at least 18%. These high transmission and reflectivity values have been achieved through careful optimization of the dye material and deposition, groove shapes and silver deposition. In addition to optimizing reflectivity, other parameters such as signal amplitude and tracking signals were also optimized to ensure full compatibility with current DVD standards.

The technology and products should become available as early as 2004. More information on this exciting development can be found here. A powerpoint presentation that explains the technology more in depth can be downloaded here.

this will kill dvd-r unless the same happens with dvd-r or the media is too expensive pity i will need to buy a new burner

This will have no effect on anything, the media will cost too much and there will be zillions of playback problems, even pressed dual layer DVDs are far from perfect with many playback issues. A blu-ray like product will be much better, all we need is some brave AV manufacture to make a DVD player that will play back DVD files from the Blu-ray disc.

And I was in nirvana state with my new PX-708A

Now I will have to replace it ?

CDR_Info reports Pioneer Corporation has proceeded to the development of dual layer recording on DVD-R discs. The first measurements on the two layer DVD-R discs showed that the jitter for the fisrt layer is 9.34%, the reflectivity 17.3%, while the same measurements for the second layer were 8.08% and 19.5%, respectively. Playback compatibility with the current DVD players is expected to be high. Although the limited information about the technology background, dual layer DVD recording is definitely a major step beyond and expected to boost the sales of DVD writers. Hmmm interesting

Don't worry too much Lord KiRon as Plextor will most likely have their 16x DVD+R recorder (PX-716A) out by then and hopefully it will be compatible with these new dual layer discs :B Until then, I too will continue to enjoy my Plextor PX-708A!!

ok, im confused--so in order to be able to write to these dual layer media- you need a new burner or no??

silentsnow: Posts: 4; Posted on: 04 Oct 03 07:03

That's right. Basically, dual-layer DVD+RW is somwhat of a different technologie compared to single-layer DVD+RW. So to burn dual-layer DVD+RW, you'll need a dual-layer DVD+RW burner and dual-layer DVD+RW disc.

Finally! Finally we'll be able to backup DVD's without stupid re-encoding and the associated quality loss. Of course we'll have to buy a new burner and probably also a new standalone DVD-Player, but heck, that's progress

wakke: Posts: 63; Posted on: 04 Oct 03 13:34

Why do you need a new burner? Since a dvd-reader can read both single and dual-layer disks I asume the laser of a single and a dual layer burner is the same, so is this not possible by firmware upgrade?

Incredible! Great! I was going to buy a 8x writer, but now... I want to write dual layer DVDs.

f_flea: Posts: 2; Posted on: 04 Oct 03 17:49

Just ordered a PX-708 and now the DVD+ R 9... I think that a writer can be adapted by means of firmware because the Powerpoint presentation of Philips states: *Modifications on firmware and application software *Standard hardware But there will be commercial issues for sure ...:B

The site said that that they used standard hardware to write to the discs though! New firmware/software was needed though.

i certainly hope so- i really dont want to know that my Pioneer DVD±rw is already out of date!:c

EDIT: Allready someone noticed the thing about no hardware-changes needed... However, the news on this page does not say that dual layer is +R only, not +RW... Would be a nice fix there, as not to confuse people

I remember DVD+RW Alliance's promise years ago, when 1st generation DVD+RW drives came out, they claimed a simple firmware upgrade will solve to write DVD+R. Was great news. Months later DVD+R was introduced, and those "great" companies just give a f*ck for their customers and wanted many of us to buy a new drive to write DVD+R. That was the biggest bullshit I have ever seen. That was more than enough of them, so went for DVD-R and have never been dissapointed since that. So I say, will belive this "software upgrade only" shit when MANY of you say that it have already WORKED. I don't belive in DVD+RW Alliance's single word anymore. regards, Stephen

Nor the DVD+RW Alliance, nor Philips, has stated that current drives will be able to record dual layer DVD+R9 media! The PowerPoint presentation only mentions that current hardware is used to demonstrate the technology. You need a NEW recorder to write to DVD+R9 media, however all current drives and players should be able to read dual layer DVD+R media recorded on other equipment, as it is designed to be compatible with the DVD-ROM standard.

Should we anticipate a problem with DVD-rot with this new media?

joex444: Posts: 72; Posted on: 05 Oct 03 02:14

did anybody else notice when they said it was 'feasible'? Maybe I have a different idea of what kind of enthusiasm is behind 'feasible,' but is that a good thing for it to be 'feasible' or not? I mean, it doesn't say 'practical'

joex444: Posts: 72; Posted on: 05 Oct 03 02:18

Ahm, forgot to mention this too: If you go to the website, they have a PDF and it says they tested it at 2.4x. That works out to just over 45 minutes a disc, for the burn alone. To gather enough data (from a pressed source....) would take atleast 12 minutes (9.6x average), so its about an hour for a whole disc at this point....

Finally some movement in the DVD burning technology.. This will mean price cuts for older models as newer ones emerge.. Im holding off for at least an 8x (Lite-On) DVD burner.. But if 16x is the goal at this point, who knows, I may wait around for that..

As stated, do you really believe they will release firmware when they can seel new hardware? By the time it is released, who knows what laws and protections may be introduced. Media rot or pure crapiness is asured - I do not believe current dvdr media will last as long as we think - so anything burnt may get corrupted years after. As for the time, so b***dy what - just how many 'backups' are you planning on making anyway. Backups - bs - kids copying endless games / movies for free and for their mates is the norm - and I do not mean the original poster, but the masses in general.

This is definitely the best news in the dvd recordable industy this year and maybe since dvd recordable was introduced. I see Pioneer has announced a similar plan with dual layer dvd-r so all is good now :B The media might be more expensive to begin with but like everything that will come down soon enough.
