Dual Layer DVD+R Developed
Lucretian writes "And they said it couldn't be done... It appears that Philips has found a way to burn a dual layered DVD+R. Unlike other dual layered disks that have been developed, this one is also designed to be backwards compatible with current DVD players. Phillips will be demonstrating this new technology at CEATEC this coming week at the DVD+RW alliance booth. The DVDs will hold 8.5GB of data (4 hours of video) and are set to be released as soon as next year."
Backing it up is simply impossible by any current means.
I personally am going to wait for the BlueRay to come down in price and go with that.
Between the current speed advantage (8x vs 4x), and now the size advantage, is there any hope for the '-R' format?
I backed up about 100GB of data a few months ago on DVD+R, and they worked fine for a few months. Now most of them are giving me CRC errors when trying to read them in any drive. I deleted the data from my hard drive to save space like a fool. I might as well have just bought another hard drive to back them up for the cost of the DVD-R media and writing drive :/
They need to research more ways to make this media last rather than try to increase the size.
8GB of dammaged data isn't good for anyone...except maybe Soviet Russia.
First, the movie industry will not like this at all, because virtually every movie will fit onto a single recordable DVD at full bitrate.
Second, the Philips technical paper does say (as expected) that a new drive is required, with an objective lens that can focus into the two recording planes on a disc.
My new DVD+R/W drive has just made reservations for the basement suite next to the 2X CDROM drive.
I don't see how you can say that -R is going to be usurped simply because of speed issues. The fact is that they could make 8x double-layer DVD-Rs if the DVD-Forum decided to make them. Also, there are very few video applications that require the double-layer standard.
/. article about it. If someone is publishing a corporate or school training video, and the viewers have an old DVD player, the chances that it will play anything but a -R are slim. Particularly with schools, it is a challenge to be replacing capital equipment even as trivial as a DVD player when budgets are so tight these days. For that reason alone, the format can't and shouldn't go away completely for the foreseeable future. But the DVD-Forum had better respond in kind and in short order, because as time goes on things will change, and +R may yet usurp this.
The fact is this: if you want maximum compatibility today with DVD readers and players, including legacy devices, you must go with DVD-R. There was even a recent
The other thing to remember is that you need to use good quality blanks with stable dyes (i.e. MAM-E/Mitsui Archive Gold, Verbatim Data Life) if you want to retain your data over the long term. Philips hasn't mass-produced these double-layer DVD+Rs yet, so we don't know about their longevity or even their real compatibility in the field. I'd take a more mature mass-storage technology over the bleeding edge, even if it meant dealing with more physical media.
I find the whole idea that people actually continue to say this phrase, absurd. In this day and age, things that were deemed impossible are being done every day. Of course this has happened throughout the ages, not just currently, but it seems more prevelant now. This is the reason I laugh my ass off when some company comes out with an "uncrackable" security mechanism.

i have one of those mini-cd mp3 players.
a mini-cd stores up to 180MB or about 25% of a standard cd.
i find this really useful for storing utilities and such, config docs, encrypted password files etc as they are small enought to fit in a jeans pocket.
now if we had a dual-layered mini-dvd i could get over 2Gb of data in my pocket!
that would be cool.
you could then pretty much fit a whole distribution on a business card!
Probably the new 8.5GB drives will cost you an arm and a leg and media will be prohibitive as well. Right know you can get a samsung ide drive of 160GB 7200rpm less than 100$. The cost per GB is not mutch higher of that of the DVDs and with DVDs you have spenf money on the burner as well. More than that the reliability of the drive is much greater, you can write and erase from as mutch as you like, speed is mutch better and to add on top it is more compact (160Gb means arround 35 dvds). Do not spend money on DVD technology.

Or conversly i'd like a distro about 1/4 the size of knoppix that could fit on a usb drive or this.

Sometimes I wonder if Sony and Philips broke from the DVD Forum on this matter as a ploy of trying to get more money. The "plus" format still isn't in the DVD standard, and they may be undercutting the DVD forum on price as a way of getting back at them for rejecting their format.
Up until Sony released their dual format drive, it looked like the plus version really was going to win, but now, almost nothing is single format.
I wish they'd just figure out a way to merge them. the dash version is slightly more compatible with set-top players and the plus version does slightly quicker packet writing.
Now, I wish that the dual layer writables would be compatible with existing writers, but at least it is supposed to be compatible with existing readers. At least broad reader compatiblity has to be there or else it won't sell quickly at the start, IMO.
