Who knew data storage could be such a pane in the glass?

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.

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.

Flight data recorders used to use lines inscribed into inconel foil. It was good for hours at 1000C.

Great Idea.

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

How can I make a small portable one?

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

holy Japan

Professor Miura Kiyotaka could change the whole internet and Digital hardcopy world - imagine how less datacenters would exist with this

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??"

hmmm

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.

😮

( Ursula keller ) made laser light tech better to do things like this .

We want 7g in India please

Until the flat edges get so scratched that lazors cant read it.

It's been 7 years already. WHERE IS IT?!!! TAKE MY MONEY AND SELL IT ME !!!

Japan a place where the technology can advance.

This is apparently the exact same thing Microsoft is developing.

Ai

Well, as long as the technology required to READ the data still exists...

Can last 300 million years…. Unless dropped

Death Stranding brought me here

Or you can say just like cd but in glass

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?

Library of Congress hiring?

this shit was stolen from microsoft
