Philips Says New Technology Boosts DVD Capacity

Dutch Philips Electronics said on Friday it had developed a new technology with Japan's Mitsubishi Kagaku Media that nearly doubles the storage capacity of data on recordable DVD discs.

Philips, Europe's largest maker of consumer electronics and lighting, said its new dual-layer technology raised the capacity of recordable DVDs (DVD+R) to 8.5 gigabytes from 4.7 gigabytes for single-layer DVD discs.

Bet the drives cost a pretty penny...

Veeeery eentaresting! :Q

I wonder how compatible this is with dvd players and other drives. It wouldn't be of much use if these discs aren't readable by other drives.

I'll have to see how well these work. Maybe yet another update to the DVD FAQ is in order....

This might be too little too late. Blu-ray looks like it might be out around the same time dual layered DVD+R. 8.5GB of storage is nice, but with 300GB hard drives out, I need more than that.

yeah, but can you play a blueray in your home dvd player like you can dvd9 ?

(edit) a salesman at Fry's told me about this two weeks ago, but I didn't believe him... I guess they do know their stuff...

That is when you buy a dual layer burner for movies and a Blu-ray recorder for more important things.

backing up the pr0n collection?

I roll my eyes every time I hear someone say this. It's not which one has more storage, it's which one is the more usefull standard. Copying dual layered movies to two discs is not good. Copying to one is good. Copying to Blu-ray is not good.

There has never been a problem creating a higher capacity format, just a problem getting it accepted. It's a good thing the industry went from CD-ROMs to DVD-ROMs and ignored all the crap in between (Dreamcast/Yamaha's GD-ROM, TDK's multi-colored die CD-Rs, Samsung's "scratch it and you're screwed" 1GB+ format, etc. The industry has ben technically capable all along). Blu-ray may become an industry standard once we need a format which can hold a digitally perfect HDTV program, but I hope it doesn't simply because it can't hold anything more than a single 2-hour HDTV video. How about a little breathing room before introducing the next format? DVD sure could have used a little more to avoid the dual-sided mess...

It looks like Pioneer decided to go ahead and announce theirs.

so will media. and i think media is a bit too expensive as it is right now.

 

[CZroe]

I think we'd all be willing to pay a little more than double the cost of standard media. Double the storage or half the discs, either way the price should double plus tack on a little extra for the conveinience.

 

[tart666]

any ideas about ETA in stores? at all? in a month, in a year, in a decade?

 

[Amorphus]

just a quick note, because I think I saw somethign about compatibility farther up:

there are multi-layer DVDs out on the commercial market already. those are the ones you can rip, but only at like 2.5x. so yes, the dual-layer DVD+Rs will play on DVD players and such.

wonder how fast the burn will be....

 

[CZroe]

Uhh, in case you didn't know: Nearly every DVD movie in existance is a dual layered DVD9 disc which, when copied, must be split onto two DVD-/+R 4.7GB DVD5 discs.

The mismatch has been a source of frustration since DVD recorders first arrived. You can only fit 2 hours of video on a DVD-R DVD5 disc if you include nothing else and lower the quality (Certainly not "Superbit").

"Dual layers" isn't a new standard for DVD players, but combined with recordable DVDs, it finally brings DVD recorders in line with pressed DVD standards

I guess that's an answer to all the people that said the dual-layer DVD+R is a serious blow to DVD-R. I think both formats will live long and happy lives.

Adding further flame to the format war fire:

Pioneer announces that it will ship its 5 millionth DVD-R/DVD-RW writer this month, a landmark that establishes the company as the clear number one manufacturer of DVD writers. The performance of Pioneer's DVD writers has contributed to the prominence of the DVD-R/DVD-RW format, which, according to TSR, accounted for 62 percent of the DVD writers shipped worldwide last year.

Can it burn this under 2 minutes?

Guess I'll have to wait for the Dual Format blue-ray/dual-layer burner

 

[krackato]

I think the Blu-Ray standard already has specs for 54gb, singled sided, dual-layer discs.

So that'll be a pretty nice format to backup to, although I wonder how expensive it'll be. The nice thing about backing up to DVD is that there's a million drives out there. In any case, maybe the future of backups is buying more harddrives. I know I'm thinking about it.

Philips and MKM to develop dual-layer DVD+R recording technology

Recorders for both the PC and consumer electronics markets are expected to become available during the course of 2004.

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.

I'm sure it's not recordable dual layer Blu-Ray. DVDs have been dual layer all along and until now there was no hope of having recordable dual layer discs... With the high densities and slim tolerances of Blu-Ray making normal dual layered techniques difficult, I doubt we'll ever see even a hint of a dual layered recordable Blu-Ray disc.
