- Hitachi has succeeded in recording and playing back digital data on fused silica. Believed capable of storing data for over 300 million years, this medium is expected to serve as a long-term storage technology that will help preserve our history, cultural heritage, official documents and other vital data.

When i was studying physics in university, i read about Hitachi working on this in my 4th Semester (around 8 years ago) and i was so intrigued by it that i wanted to try it myself. I got 3 friends studying with me and we decided to try to use glass as a data storage medium during a one Semester project to find out if this was actually doable. We looked for a research institute with the right equipment (we found one with a picosecond pulse laser that seemed good enough), came up with a very simple digital format und burned some simple information into glass. In the end we concluded, that the biggest obstacle would be data density but that the sheer permanence of this approach (being far superior to disc drives, flash drives and optical medium) was well suited for data archiving where reading and writing speeds (and rewritability) doesnt matter that much. Unfortunately i haven't heard much since regarding this technology that convinces me that it will be used any time soon. I hope this will eventually a commercially viable option for long term data storage for especially sensitive information.
Sure, you could store tiny QR codes on plastic sheets...
Microsoft have it. It's called Project Silica
Hitachi invented it three years ago everyone forgot. Microsoft did it a few days ago paid CNET to promote them as if they did it.
Exactly
How much did Microsoft paid Hitachi ????
And it lasts way longer than the Microsoft's one.
Bill Gates also bought their nuclear reactor design.
Oh, and I've been hearing about this kind of tech since about 1997. I don't think it will ever be available to the public.
Who knew data storage could be such a pane in the glass?
A clear' look, into information' transparency.
Flight data recorders used to use lines inscribed into inconel foil. It was good for hours at 1000C.
Tadesan
That's amazing!
probably wire is not dense enough to store terabytes of data.
They can recorded the data to the Fuzed silica through the laser on its side one tiny lines one terabyte each that can seen on the fronth and it can be purified by the reflectors on one side
Is this the same technology 5D memory device invented by Peter kazansky which also uses femtosecond laser to write data inside the glass or hitachi discovered the new way or new material to store data i am confused who actually discovered the idea of storing data inside the Glass using femtosecond laser if anyone has an answer plz let me know
It doesn't seem to be 5D as they are just storing a single bit rather than exploiting polarity and amplitude. Microsoft's project Silica on the other hand can store multiple bits into a single voxel.
I could see some aliens finding that quartz plaque floating through space, one day...
Alien : "Oh look, how adorable! It's from Earth!" =D
Alien's Friend : "What is it?... and who the f#ck is Earth??"
Professor Miura Kiyotaka could change the whole internet and Digital hardcopy world - imagine how less datacenters would exist with this
holy Japan
Quite frankly look at a solution to replace the polycarbonate layer on M-Disc with Silica Glass or some other material that wont degrade over time, You don't need to waste money and resources on a new technology to store data and read it.
How can I make a small portable one?
This is apparently the exact same thing Microsoft is developing.
Great Idea.
It's been 7 years already. WHERE IS IT?!!! TAKE MY MONEY AND SELL IT ME !!!
2029,so prepare your money.
@@gregandark8571 Really?! I will look into it. Thanks!
@@Santiago_Handle This technology will be available when Heavenly Jerusalem will finally be established in Ukraine.
A lot of things in 2030 are gonna change ...
( Ursula keller ) made laser light tech better to do things like this .
Japan a place where the technology can advance.
Well, as long as the technology required to READ the data still exists...
I don't think it's hard to re-invent a microscope
😮
Until the flat edges get so scratched that lazors cant read it.
We want 7g in India please
Death Stranding brought me here
Can last 300 million years…. Unless dropped
I compared nanotechnology optic computers with the 4 quadrillion ton diamond carbon memories. It must think? It must etch records like your almost deified technology. My window panes are 3 mmm thicker at the base after many years of gravity....is your glass special?
My wife’s diamond is etched with a serial number. Am I missing something?
hmmm
Or you can say just like cd but in glass
Library of Congress hiring?
Ai
this shit was stolen from microsoft
It was not, Hitachi has been working on this for at least a decade now (most likely longer). When i researched this technology 8 years ago, there was no mentioning of Microsoft working on it anywhere. So if it was stolen at all, the it was probably the other way around.
In history nothing is stolen from Microsoft, it's Microsoft who stolen from others.
