Hitachi Creates Quartz Glass Archival Medium 116

guttentag writes "Hitachi has announced (original press release in Japanese, translated to English) a new storage medium that uses a laser to imprint dots on a piece of quartz glass that correspond to binary code. The dots can be read with an optical microscope and appropriate software. The company says this medium is resistant to extreme heat, radiation, radio waves and should still be readable after a few hundred million years. It's intended as an archival format with data density similar to a music CD (40MB per square inch with 4 layers)."

The strange pattern will also attract the interest of future scientists, who will probe at it with reinvented microscopes until they figure it out.

      • Learn to read. It's 40 MB per square inch. Same as an Audio CD. You could easily fit music on something the size of an audio CD, I'm sure someone has done it before. Although pictures are getting quite big. A single picture from my digital camera comes pretty close to the size of a lot of MP3s I have. So, it might need quite a few of these discs to back up the thousands of pictures I have. Although you could probably keep a collection of important ones.

        I propose writing on titanium or aluminum sheets. Most of the writing would be in tiny microscopic font to get some decent data density -- like microfilm of the 80's, but with better long-term durability.

        On the first page we could put normal-size writing as sort of a primer. Then the text would get progressively smaller until it's microfilm-sized, so the reader would get the point that the rest of the tablet is in tiny letters. We could put a diagram explaining the properties of a magnifying glass, and how to make one.

        A bit like the plans for the Rosetta Project: http://rosettaproject.org/disk/concept/ [rosettaproject.org]

        The surface starts with a visible circle, 1 mm in diameter. The next circle is a bit smaller. The next is smaller still, and so on until the size of the bit is reached. This would draw somebody examining the device to trying to see where this detail ends.

    The problem with long term data archival isn't just the storage medium -- it's being able to recreate the reader mechanism from scratch. Tomorrow world war 3 happens. We're bombed back to the stone age. Thousands of years from now, humanity has returned to the level it is today, but with no knowledge or intact examples of previous technology. How do you explain how to build something, when the language, the words, and the understanding of physics and technology are all different (and possibly wrong or incomplete)?

    We've been trying for a long time to come up with a universal language; Partly in case we ever contact E.T., but also because of the problem of language fragmentation. Human language tends to diverge, not converge. How do you manage to tell someone how to construct a complex device from scratch, without any linguistic foundation and scientific understanding to build from?

    • The problem with long term data archival isn't just the storage medium -- it's being able to recreate the reader mechanism from scratch.

      These are two different problems. One is how to archive things assuming the future will be technologically proficient, another is how to archive things assuming it won't. This technology is clearly geared towards the former. In a technologically proficient future, historians will certainly love having full access to the tons of small details and day-to-day stuff that can be made available for them with this, things we wouldn't dream even trying to archive in something geared towards a technologically backwa

Historians believe that a catacalysmic nuclear event several thousand years ago was what caused the Great Warming. Records show a language known as "english" was prevalent in the worst-affected areas. It was retroactively banned by the 320th High Pope of the New New Pastarastafarian church. It's believed the language itself was what caused the problem. Your argument is invalid.

Next to the "red" picture, put a label indicating that this is "red" or a specific reddish wavelength of light. Ditto green

    For time frames of less than 1000 years and assuming no major disruption like a nuclear war, we can assume that people will know what binary code is, what the English language is, have bodies that have eyes and ears that respond to light and sound much the way ours do now, etc. This makes deciding how to store information much, much easier.

    The Rosetta Disk fits in the palm of your hand, yet it contains over 13,000 pages of information on over 1,500 human languages. The pages are microscopically etched and then electroformed in solid nickel, a process that raises the text very slightly - about 100 nanometers - off of the surface of the disk. Each page is only 400 microns across - about the width of 5 human hairs - and can be read through a microscope at 650X as clearly as you would from print in a book. Individual pages are visible at a much lower magnification of 100X. The outer ring of text reads "Languages of the World" in eight major world languages.
