TOPPAN and Sony Successfully Develop 25GB Paper Disc
Tokyo, Japan, Apr 15, 2004 - (JCN Newswire) - TOPPAN PRINTING CO., LTD (TSE: 7911) and Sony Corporation (TSE: 6758) today announce the successful development of a 25GB paper disc based on Blu-ray Disc technology. Details will be announced at the Optical Data Storage 2004 conference to be held from April 18th to April 21st at Monterey, California.
Using the disc-structure of Blu-ray Disc technology, the new paper disc has a total weight that is 51% paper. The two companies jointly began this optical disc project approximately a year ago. Blu-ray Disc is commonly known for allowing more than 2 hours of high-definition program recording.
Hideaki Kawai, Managing Director, Head of Corporate R&D Division, TOPPAN CO., LTD commented: "Using printing technology on paper allows a high level of artistic label printing on the optical disc. Since a paper disc can be cut by scissors easily, it is simple to preserve data security when disposing of the disc".
Masanobu Yamamoto, Senior General Manager of Optical System Development Gp., Optical Disc Development Div., Sony Corporation said: "Since the Blu-ray Disc does not require laser light to travel through the substrate, we were able to develop this paper disc. By increasing the capacity of the disc we can decrease the amount of raw material used per unit of information."
The worldwide production of optical discs is approximately 20 billion per year and optical discs are being adopted widely. The combination of paper material and printing technology is also expected to lead to a reduction in cost per disc and will expand usage.
TOPPAN and Sony will continue development of the disc for practical use.

It's a moot issue anyways... DVD's go through the office paper shredder just fine... the crosscut here that handles 10 sheets at a time destroys CD's and DVD's on a regular basis.
Do not look at laser with remaining good eye.

"Using the disc-structure of Blu-ray Disc technology, the new paper disc has a total weight that is 51% paper"
Its kinda like saying WinBlows is better then Linux, but after reading the fine print: "the systems were judged by 100 people, 51 being microsoft employees..."
Yes its paper under the text books (congrats on pulling it off) but then again its also 49% not paper, probably good old plastics...
They're merely blocking the referrer.
i think you have your units mixed up.

true 25GB isn't enought space for the LoTR super-extended-extra-long-aren't-you-glad-you can-pause-it-to-go-to-the-bathroom edition
but a normal DVD hold 7.9GB and a DVD-R holds 4.7GB, some DVDs hold up to 15GBs

exactly how long will this paper last before it starts decomposing in some way?
Paper doesn't really decompose unless it's subjected to bacteria, air, water, dirt and stuff.
High quality paper, such as wood-free paper doesn't even yellow much in sunlight.
(Wood-free? You say.. that's paper which is 100% cellulose, with no lignin in it.. lignin is the stuff that separates trees from plants.. without lignin, it's not wood, hence 'wood-free' paper.)
In a good environment (as one could expect for this kind of purpose) paper should have a far greater life-span than any hard drive I've ever owned.
(and I've held on to some of mine for quite some time)
They tried stuff like this, it sucked.
Note, that's not to be confused with the DivX standard used by those nasty "pirates". There are other types of disposable DVDs floating around. The main one that comes to mind now is the one that oxidizes when you open the package.
Anyway, it especially pissed off the Slashdot crowd.
Down with Saudi Arabia!!!
And if you go for something a bit snazzier printer wise like the Epson Color Proofer 7600 you get:
... you have a scanner?"
2880 dpi is 2880x2880 dots per sqaure inch
You have 8.5 x 11 square inches (or pi * 2^2 for a cd sized area)
You have 7 individual colors so lets count a dot for each, and lets go with no error correction (just to get a maximum conceivable).
You end up with 14M / square inch, a big improvement over 9k!
That would give you 1.3G / double sided page, or 182M / double sided cd size.
So Sony's tech here is nearly as big a leap up again as from 300x300dpi@1bit to 2880x2880dpi@7bit! It's a long way from printing quality (forget the fact that you would need to be incredibly redundant to make it any use, forget 10 bit bytes, i'd be thinking 64 bit bytes if it's meant to be lossless storage on the scheme I outlined). Might be fun to try and print out and scan back in say a knoppix cd in as few pages as possible, "what you mean you don't have a cd drive
Never underestimate the dark side of the Source
And I'd be a Libertarian, if they weren't all a bunch of tax-dodging professional whiners.

Actually the Blu-Ray discs hold 25GB in a single sided, single layer medium. That's one of the reasons that they can use a paper disc, the laser beam doesn't have to travel beyond the initial recording medium to a second layer.
The smaller (physically) and the bigger (data capacity) that magnetic media gets, the harder it is to destroy (by magnetic field).
Vastly simplified (and too heavily parenthesized) explaination follows: All things being equal, if you pack bits closer together on a magnentic substrate they are more likely to smear into each other causing data loss. To combat that, when increasing bit density, you need to raise the strength of (applied) field required to cause a change in (media) field orientation. This is done primarily by changing the chemistry of the media. In order to overcome this increased resistance to change, you generally will need to either increase field strength in the write head (in most cases this means making the head more massive - as generally you've already used the strongest [field strength to mass ratio] design you can find) -- OR moving the head closer to the media (the usual solution - often this also means making the head smaller {which by the way, makes it more robust in terms of shock resistance not less, contrary to common assumption}).
What all this means is that you generally can't afford to buy an electromagnet capable of erasing a laptop hard drive. You would likely be looking at an industrial power feed from the electric company. In short, a chipper/shredder ment to be fed hard drives is a much cheaper/easer way to do it.
Why do I know about any of this? When we switched from 1600dpi to 6250dpi reel-to-reel tapes for backup, we found that our handheld "bulk tape eraser" wasn't doing anything any more - so I did some reading on why. Now, the hard drive in my laptop isn't much special (Toshiba MK4018GAS) - Toshiba's tech spec for this (pg 11 under General Description) lists a density of 35.1Gbit per square inch. Our reel-to-reel tapes had density listed as a liner spec, not area, so if I take the square root of the drive density -- coming out with a guess of ~187K dpi linear density (this is not quite the right way to go about it, but will do for now). As you can see - roughly a hundred-fold density increase over where the threshold of "bulk tape eraser" will do you much good. I do not know the formulas to calculate the field strength you need to erase at that density - hence the actual size of the electromagnet you would need.
but it doesn't record to paper plates
My wording could have been more clear. The 1541 ACTED like it formatted a paper plate. You'd have to cut the plate, or other piece of cardboard to size, place it in the drive, and then run the format operation. This would proceed and conclude with no error message. This does not mean that the resulting paper disc was ready for Commodore data storage!
Don't blame Durga. I voted for Centauri.
Eh -- problem here is that 7 colour != 7 bit, because if you add black to any of them you still have black. 7 colours is more like 3 bit, e.g. there are 8 distinct and detectable values: black, cyan, magenta, yellow, blue, red, green and white.
This also discounts bleed, cueing and error correction.
