Skip to comments.Sony Innovating In Tape Technology… Seriously (185 Tera Bytes )
Posted on 05/09/2014 10:07:31 AM PDT by Ernest_at_the_Beach
Sony is making some waves in (believe it, or not) magnetic tape technology. Reaching a maximum capacity of an astounding 185TB, Sony hit a world record in data density of 148GB per square inch. This massively outpaces the current industry standard LTO variants density rate of 2GB per square inch as well as maximum capacity by a factor of 70. This means that my entire collection of Ultrium 3s at 800GB could be contained on a single cartridge of Sonys new tape with space for another 13 years worth of backups.
Sony detailed the fine workings in their press release:
Sony has developed a new vacuum thin film forming technology which is able to form extremely fine crystal particles with the aim of creating a practical, next generation tape storage media. This newly developed magnetic tape technology uses sputter deposition, a type of vacuum thin film forming technology, to generate multiple layers of crystals with a uniform orientation on a polymer film with thickness of less than 5 micrometers. Until now, when the sputter method was used to deposit a thin film of fine magnetic particles on a polymer film, roughness on the surface of the soft magnetic underlayer caused the orientation of the crystals in the underlayer above it to become non-uniform. This in turn caused non-uniform crystalline orientation and variations in the size of the magnetic particles (grain) in the nano-grained magnetic layer directly above the underlayer, and prevented increases in recording densities. By optimizing sputter conditions and independently developing a soft magnetic underlayer with a smooth interface, Sony has made it possible to minimize disparities in crystalline length and growth. This enabled Sony to create a nano-grained magnetic layer composed of fine magnetic particles with an average size of 7.7 nm. When the magnetic tape created using this technology was measured and evaluated using an exploratory recording and assessment device, this new media was shown to achieve the worlds highest areal recording density of 148 Gb/in2, equivalent to approximately 74 times the capacity of conventional coated tape media for data storage.
The breakthrough comes at a time where even Facebook, maintaining the worlds largest collection of biometric data and images, suggested that Sonys Blu-Ray was the most efficient method of cold storage on the market. At Open Compute, Facebook VP of infrastructure engineering Jay Parikh cited the 50% cost reduction and 80% increase in energy efficiency as a reason to switch non-essential data storage to BRD. With todays tapes running about five cents per gigabyte, Id be surprised to see BRD outperform Sonys new format in either cost or energy. Speed would likely be the only crutch, but unfortunately theres no official word from Sony on read/write speeds. Sony says that theyre definitely looking to commercialize the new tapes as well as pushing their record breaking density.
Get you cameras working.
But won’t it take like several hours to fast forward or rewind to the section you want?
Hopefully, it will mean the handful of shares I kept when I left the company in 2008 will be worth what it was when I left.
Believe it or not, there is still a fair market for cassette tapes in some third world markets and Sony still makes those tapes, too.
I’d hate to have to wait for that tape to backup my system.I’ll die of old age before it’s done.
Recording density of 148 Gb/in2. Holy smokes. That is very impressive indeed.
That’s a lot of pr0n.
And the NSA rejoices.
This tape would back up several TB of data in seconds.
Now we need that on a rotating surface
If that tape machine is able to recover that fast that would be a great piece of backup gear.I have had tapes in the past that we’re slowww.
I would prefer the disk method.They seem to be much faster.
If you could apply this technology to DVDs, that would be about 1.5 Tb per DVD single side. Far better than the 15 Gig for a single side HD-DVD.
Trying to find a picture of the IBM Datacell....it was incredible n its day....
This is a magnetic technology ..tape, floppy disk, hard disk drives
cd, dvd, blueray is optical tecnology
That is technically enough to back up a person’s brain!!!
Suely one of the plants is digging out their blueprints from years ago...
Are y0u kidding?
Are y0u a m0r0n?
The magnetic film strip was wound by mechanical means and kept in the round plastic cartridge seen beside the tape reel.
There was a follow on ot this box A real mechanical marvel....
Need another picture....different source:
...as Sony seems to not want to let people know what the read/write speeds are.
As the author here aptly questions
"First and foremost is the matter of read/write speed on these cassettes. How quickly will they record your data, and more importantly, how quickly will you be able to access your data if you need it in a pinch? Chances are that the answers to those questions arent all that positive, especially considering that current LTO tapes read/write speeds range from 150-400MB/s depending on the compression of the data being transferred."There is a reason tape drives went the wayside for most in IT once storage capacity on disc became cheaper...
And furthermore, I'm still pretty pissed off at Sony for killing HDDVD...
Your follow up picture posts do bring back some memories.
