100 Terabyte 3.5-inch Optical Storage
ignipotentis writes "According to PhysOrg we are close to being able to record our entire lives on a single 3.5" optical disc. This article talks about using ultraviolet light since focused laser beam is smaller in diameter than other frequencies of light. The expected cost per drive upon production is $570-$750 with discs costing $45."
The graphic in the article says 10 petabyte, not 100 terabyte. That's a factor of 100 different.
Also, the second graphic refers to Seagate and "Maxstor"... perhaps they mean Maxtor?
If Colossal Storage Corp. can't even get their infographics right, I don't know what that says about their ability to make these drives.
http://www.colossalstorage.net/ -- it's pretty ghetto, in a circa 1996 sort of way. Animated GIFs abound.
well not just radiation, if it is just a single molocule, what prevents entropy from scrambling the data? all you'd have to do is heat it and boom its all scrambled
If I trust what I learned with the 12cm optical disks I currently use (CDRs), my entire life would last about 2 years before getting unreadable.
Frankly, if you've CDR's that have gone unreadable in 2 years then you must have somehow mishandled them or gotten a bad batch. One of my friends lost a bunch of photos because he had accidentally marked them with a marker that contained solvent.
However, correctly handled, the CD-R:s should last quite long. I've a few that are over 10 years old (burned back in 1993 with a single-speed CD-R-drive or something like that). And they still work just fine. I've never had a CD-R fail on me except during the burning phase.
Oh, incidentally, one of those CD's from -93 contains all the stuff I had with my 5 1/4" floppies. Upgrade your data to a better media if necessary. However, I would thing that the CD-sized optical disc remains readable for quite a long time. The form-factor is just so...convenient that future standards will probably use it, so your HD-DVD and Bluray drives can read CD:s just fine.
Existing magnetic drives already write bits multiple times in succession to guard against corruption, and CD technology has error correction as part of the standard.
Well, This paper would suggest that such a ferroelectric disk would be resistant to stray electromagnetic fields.
There's a rather old technology for doing a spawn/merge of your body together with somebody else's. There's some additional details, with graphics, here.
That's about 5 Libraries of Congress (at 20 TB per LOC) Oh wait, you wanted a unit that was easier to understand....
"thru" is a word http://www.onelook.com/?w=thru invented by the author of the Dewey decimal system.

60 degree ultra hi-res ?
Angle of view is about 150 degrees, but hi-res is only about 2 degrees in the middle.
The rest you could cover with a low-res mpeg.
I'm guessing that wasn't on their radar screen...
Heheh.. and imagine when the first write-speed is 1x, measured similarily as with cd's (realtime music playback) or dvd's (realtime video playback). It will take a lifetime just to record it.. :-)
make me wonder if either an editor of PhysOrg had a fun time being bought off
From other evidence it looks like PhysOrg is part of the scam. Have you read their "whitepaper"?
The holographic optical drive will use the Einstein/Planck Theory of Energy Quantum Electrons to control molecular properties by an atom's electron movement/displacement. The FeDrive - FeHead Semiconductor Integrated Optical Read / Write Head plans to use lenseless Ultraviolet/Blue laser diodes with Voltage transducer to write, new definition of the term include photon induced electrical field poling...

Disclaimer: IANAP, but I try to keep my chops in 20 years after leaving college.
Judging from the article, it sounds as if the drive would require a 50nm laser source. There are no cheap semiconductor lasers available for this length and never will be. And I doubt you'd want to have an excimer laser in your data drive. In addition to that it would imply that the disk has to be read in vacuum... Veeery fishy.
In addition I refard physorg.com as a highly unprofessional site. They spam the usenet and various web forums a lot. They also have the nerve to steal entire threads(!!) from the usenet and insert them to their forum, so it looks populated.
According to the guy who runs the Internet Archive, sorry I don't have the link to the interview, but it is out there somwhere, he estimated that the sum total of studio recorded audio in existence was 160TB the vast majority not being from the US. So, you'd need ninety bucks worth of media.
He also quoted a surprisingly small number for movies which mostly comes from India apparently and he separated movies and video into two categories. It was a fascinating interview.
