The new Digital Rosetta Stone (DRS) memory, invented in Japan, can store data for over 1,000 years. Currently optical is the best long-term storage format, but it degrades within 100 years or less.  (Source: techshout.com)
This is one LONG term storage solution

Memory longevity is a touchy subject that most businesses, researchers, and consumers purposefully ignore.  Magnetic drives, in theory, are thought to be corrupted in about 40 years due to the Earth's magnetic field, though this has not been fully observed yet (hard drives have only seen widespread since the 80s).  Optical discs, such as CDs and DVDs are expected to become corrupt in about 30-100 years, if not kept out of contact with moisture and oxygen.

So if we wanted to store something for more than a century, there are few good current solutions.  Until now, that is; Japanese researchers have come up with a new form of ultra-long term memory that they say can last over 1,000 years.  They dub their memory the Digital Rosetta Stone, or DRS memory for short.

The system consists of a stack of four 15-inch wafers, each containing special memory chips.  The wafers are sealed with SiO2 and SiN to insulate them from oxygen gas and water.  This key feature maintains the humidity at below 2 percent, essentially allowing the long life.  The wafers will be built on a 45nm CMOS technology and offer 2.5 Tbits of total memory capacity

In order to get at the memory and read from and write to it, researchers use a electron-beam direct-writing technology. A mask ROM on the chips provides inductive coupling and allows contactless communication.

The test prototype used larger scale 0.18μm CMOS technology and 5mm x 5mm test chips.  With the reader and the wafers separated from contact by 0.2 mm, a four-channel communication speed of 150Mbps was achieved, using only 56mW of power.

Researchers hope the system will be used to protect mankind's most precious and critical digital data.  In time the technology may see its way into the mainstream as well, serving as a backup for important business or consumer information.

Format changees faster than storage

so what? It's not like we or anyone else will be able to access that data 1k years from now.

It would have to be transferred onto a more modern format long before then. and then again, and again, and again.

How easy is it to read 5.5 Floppy these days? 3.5? ...how long before CDs and DVDs are.

Seriously, what's the point of long-term storage when storage formats, based on current data, tend to go extinct every 15-20 years?

If a format gets standardized as "long term archival", I assume hardware for reading it would keep on being produced.

And if a format is old enough, custom making a reading device could be an option. I think if someone today wanted to make a reader for 8" floppies, and even more so an electronics company, it could conceivably be done with cheap off-the-self parts.

The beginnings of "Data Archeoligists" exist now. A friend (professional librarian) has shown me an extensive document on data archiving from the International Association of Sound and Audiovisual Archives (website http://www.iasa-web.org ) dealing with such issues over the time frame of the last century. You'd be amazed at the complexity of reading information from non-standardized systems and equipment that no longer exists, even over such a short time frame. From that experience the group is dealing with how we can store data so that it can last a while and be reproduced accurately in future.

Regarding ability to discern the original meaning, I'm reminded of a scene from the novel, "A Canticle for Liebowitz" by Walter M.Miller, Jr. (See http://en.wikipedia.org/wiki/A_Canticle_for_Leibow... ). My sketchy recollection is that in a post-nuclear-war society that operates rather like the European middle ages, the monks have found and preserved a relic from a great scientist, Liebowitz, which they do not understand yet. It is a scrap of paper bearing words like "bagels" and "cream cheese".

I think storage that lasts 1,000 years could be a good thing. But I am not so sure about prediction that hard drives will fail in about 40 years due to the earth’s magnetic field. People have tested hard drives to destruction and they are surprisingly tough things to destroy.

One computer magazine was testing how robust an average hard drive is. They subjected one hard drive to a large electromagnet that is normally for picking up and moving scrapped cars in a junkyard. The hard drive still worked afterwards and the data was intact.

As for reading the data on the disk. We might want to seal the data in a vault, along with the computer hardware and software to read it again after a millennium. A computerized time capsule.

I also heard recently about an emulator that is being put together, that will read data from any computer format, going right back to the early days of computing.

zinfamous, you've been had by what I like to call 'the pseudo intellectual'. Perhaps you read it somewhere? Perhaps a friend tried to explain it to you. Sure, it all seems very logical what you just said.

Very logical unless you're an engineer. Or a biologist. Or a chemist. Or just about any similar field that realizes that the only real thing that changes in technology is how information is accessed. Electricity isn't going to change. Metal is still going to be made of roughly the same chemistry, and an engineer 1000 years in the future, unless we destroy ourselves by then, will no doubt have ample ways to simply scan the piece of hardware and extract data from it. No need for USB. No need for 802.11n.

So before we go off BSing that we cant even get that info in 1000 years because we would have no way to access it, try to understand that just because you are too lazy/stupid to think of a way to access that old 5.25 floppy from your armchair, it doesn't mean no one is.

How?

Capacity is the answer. How many bits of information survives from those times? Not too much.

With digitial long term archiving you can save much more... plus the more gives you the chance to save different kinds of data. You can save languages - see how they change over time. All sorts of sounds. You can save photographs and movies. How many sounds from the past do you know to have survived? Do you know of any photographs too? So on and so on...

How do these researches know that the data will last 1000 years? All I could find out from the link is that it somehow regulates the atmosphere. Does anyone know how these researches came up with 1000 years?

To me, it seems like we could use some sort of optical medium and put it in a vacuum. Would that protect the data as well as this?

Can anybody help me out please?

I didn't read anything about it besides this article, but I'm guessing extrapolation from accelerated aging tests. Run 1,000 chips in a room at 100C with high humidity, maybe changing the conditions rapidly, or to other extremes, and see how many fail after a day or two or a week.

Umm... does the equipment needed to read, decode, and use data out from that storage also last 1,000 years?

If a floppy disk could somehow keep data for 1,000 years but if there hadn't been a working floppy drive for 980 years nor anything that would attach and use such a drive for 970 years, what good would the data on it do?

This sort of thing has been argued to death regarding film vs digital photography. Argument for things like Kodachrome that lasts for a very very very long time (albeit anybody wanting to use it need to do so this year before stocks run out, now that it has been canceled) is that it takes no auxiliary equipment to know what the storage is nor to extract the data (a Kodachrome slide can be looked at directly w/nothing but one's eyes).

That's part of the problem we're having today. We have the tapes but the equipment is getting harder and harder to find to replay the media so it can be converted.

The big issue is format. Will software know what to do with 1000 year old JPEG files? Will anyone know what a PDF file is, let alone how to turn one back into an image.

If you plan on implementing this you'll need to make sure that you include the software to run it and hope that software would run on computer systems 10 years from now, let alone 1000.

In reality you need to move your data to new formats frequently and keep it up to date, otherwise what good is that ProWrite file from 20 years ago with the meaning of life and everything on it when Word 2007 doesn't know how to open it?


Best long-term storage?

quote:
Currently optical is the best long-term storage format, but it degrades within 100 years or less. (Source: techshout.com)


First off, optical is not a storage "format" per se. It simply means data is literally read from a medium using an optical sensor.

Optical discs, with the most common being CDs, DVDs, and BDs, are a storage format. CDs and DVDs both have theoretical lifespans of 100 years, but most CDs will in fact last closer to 20, while most DVDs closer to 30. Some CDs have been known to degrade in under 20 years.

For all intents and purposes, good CDs and DVDs will last well over 50 years if not over a hundred, which is fine for a good portion of archival usage, but not all. Museums, libraries, and others will need digital storage that lasts hundreds of years.

In any case, that caption is simply wrong. Paper and ink is the best long-term storage solution by far. The right ink and surface will last for hundreds, maybe thousands of years.

I was wondering, does the plastic on the CD/DVD degrade, or does the actual film the data is written on. If its the latter... couldn't you simply sandwich the written surface between two plastic disks creating an air tight seal?

The rate we are going in the world today -- I'm not so convinced their will be a human species in a thousand years time, or at least a significant one at least.

But perhaps its also just a normal cycle that during each person's particular time on this planet they feel is near the end of the species ....

Anyway, I tend to agree with the person who wrote will it really matter when data standards change every decade or so. I do get the logic of "well I'm sure they can just build a device to decrypt it".....I'm sure they could too -- but I don't think it would be easy.

Remember you have to think very very long term, its not like trying to find a part today for a '57 Chevy....we are talking 1000 years out. You really think even something as simple today as a USB cable will be numerous and plentiful in 1000 years? You are lucky if even one remains on the planet. Let alone today's logic boards or optics in DVD or Blu-ray players.

On the other side of the coin, if they could --- schools and libraries would be much more fascinating than today.... think about it --- don't you think if we had actual clear video footage of say the American Revolution or even the Civil War that kids would be far more interested in learning aobut it?

I know I would...but I like those subjects anyway.

I mean think of all the moments you ever thought about the history of any event and were like "I wonder what that looked like? I wonder what that must have been like? I wonder what that person really looked like?".....well if you could store 1080p quality video from today for viewing in 1000 years....those folks won't have to wonder....they can see what today looks like and the popular figures of today.

I think that would be pretty cool...

What is the point of something that can hold data for a thousand years? Eventually something else will come along and replace it, and probably in the next 30 years or so, and then that tech will be replaced, and then that one and so on and so forth.

The only way this thing seems likely to actually store data for a thousand years is if technological society falls then rebuilds after several hundred years. But then they most likely won't even know how to access this particular type of device anyway. Even if they can acess it, what are the odds that they will be able to translate it. And i'm not talking about simple language transaltion, but the more abstract translation of bits and bytes themselves. They won't necessarily have the same 8 bits per byte or file types we have today. They wont't be able to tell what is file header and what is actual info or even where on file begisn and another ends. So unless that info is stored in some more rudimentary place, like etched in stone, there is no way they will be able to read this.

Cool about the teensy power usage though.
