Wow...
by Willy - 5/21/09 10:33 AM In reply to: 12 TB on a DVD? by CoryphaeusI told someone last week, how I used to fix 300mb CDC drives. These were the size of washing machines as a reference. Now, I carry a 8gb flash drive and that's equal to approx. 27x300mb of those drives. Those filled a room and here I am carrying a flash drive the pack of chewing gum in my case. Times do change.

Hey Willy...
by dminott - 5/22/09 7:21 PM In reply to: Wow... by WillyWhen my company sent me to CDC school to learn how to repair those "washing machines" they told us of a guy that was almost killed by one! He was standing behind the drive, with the cover off, when the head assembly quickly retracted , driving the steel rod through his belly!
Afetr that, they added a thick steel plate to the end of the assembly to prevent another occurance!
I spent many unhappy hours analyzing the surface of those disk packs looking for "hits!"
Bring it on.

This news blows my mind. I guess it shouldn’t, as someone who’s seen the advancements in computers in my short 26 years, but seriously, this is nuts. I can’t wait.

It's incredible

We had a report on it on our morning show here in Australia where it's being developed.
It seems the 2000 video's on a single disk is just a starting point.
Where current lasers use only a single color laser, using the nano technolegy the full color spectrom can be used.
I hope I live long enogh to see it appear fitted in new computers.
I thought I was in heaven when I moved from a compter that was running dos 2 off 2 x 5.25 inch 360kb floppy disks to one that had a 10 megabyte hdd.
More . . .
by Coryphaeus - 5/21/09 4:34 PM In reply to: It's incredible by Jonmor68A while back, NIST described the discovery of a certain molecule (cesium I believe) that could be in as many as four states. Think about it. Storage on the molecular level, four bits per molecule.
Lifehacker is going to have a field day...

You guys are blowing my mind right now. Think about what this means in the way of clearing up space around your house. Lifehacker is going to have a field day when people are consolidating stacks of Blu Ray discs into a tiny stack…
Cheers,
Good old days
by mwooge - 5/25/09 6:10 AM In reply to: It's incredible by Jonmor68Ah, yes. The good old days.
My first permanent storage was cassette tapes. After that 160kb, 5 1/4" floppies. These were single-sided, but you could modify them with a paper punch to make them "flippies".
The first HD I saw was a full-size drive. It held 5 megs, which we all thought was huge. And it was, for the times.
Logarithmic Expansion
by dminott - 5/22/09 7:30 PM In reply to: 12 TB on a DVD? by CoryphaeusOur store of knowledge is increasing at a logarithmic rate and our storage capacity better follow suit. That's the easy part.
The hard part is going to be how to access that information in an efficient manner. Today's technology (i.e. Google) is only a baby step.
we are going to need search algorithms that can differentiate information stored in images, for example. Now, we must add "tags" to images for surch purposes... a slow and inconvenient method.
We will need to be able to have exotic pattern recognition algorithms
that can "recognize" requested information. That will be a real breakthrough! Yes, there is some rudimentary work already done in this direction, but it must expand quickly!

Well...
by Flatworm - 5/23/09 7:14 AM In reply to: 12 TB on a DVD? by CoryphaeusI am a bit skeptical (although I admit that I have been skeptical about new technologies before and have been wrong about it) that the cost of these disks can be brought down to competitive levels. I mean, you can get blank DVD5s now for a dime apiece sometimes.
Blank Blu-Ray disks are still too expensive to make much penetration in the consumer market (although the price is falling FAST, and you now can get them for about $3.00 each), but I read several years ago -- before Blu-Ray players were even on the market yet -- that researchers had succeeded in recording and playing back FIFTY layers onto a single BD. That's about 12.5 terabytes without the fancy nanotechnology-based media.
