Titanium Oxide For High-Density Optical Storage
Stoobalou and other readers sent along word of research out of Japan, using a new crystal form of titanium oxide for high-density data storage — promising discs that store 1,000 times more data than Blu-ray does today, up to 25 TB. The material transforms from a black-colored metal state that conducts electricity into a brown semiconductor when hit by light, at room temperature. Titanium oxide's market price is about one-hundredth that of the rare element that is currently used in rewritable Blu-ray discs and DVDs. The material is cheap and safe, and is already being used in many products ranging from face powder to white paint. The researchers successfully created the material in particles measuring as small as 5 nanometers in diameter.
This state change also changes its reflectivity, similar to how a CD-RW works.

Escher was the first MC and Giger invented the HR department.
Are there any projections/estimates related to how stable this media would be when used for long-term archival storage?

I have been waiting for affordable removable storage in the TB size range for many years now! There's a giant p0^H^H document library waiting on my NAS to be archived ...
The full 1000x potential won't be extracted straight away, we may see this technology in the next generation x2 or x5 the density. Now that Big Content has found a reason for more capacity with 3D, and a reason to make your existing movie collection obsolete, they will be looking for the sucessor for blu-ray 3-4 years down the track (because honestly it hasn't taken over from DVDs yet).
Interestingly in CD-ROM's heyday it wasn't uncommon for a PC to have a smaller hard drive than the amount of data that would fit on a CD-ROM. About the time DVD-ROMs were out I suppose hard drives were only a little larger. Blue-rays were fraction the size of a hard drive when the format spec was finalized (2005). Now hard drives are 20-40x larger than a blu-ray disc.
Carelessly extrapolating from the trend I predict we might not see this technology in widespread use until a common consumer hard drive is past the 25TB mark.
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
TFA and TFS both refer to "Titanium oxide" which typically means either TiO or Ti2O3 (Ti in either II or III states). However, both TFS and TFA also assert that the "Titanium oxide" is used in sunscreen and suchlike, which implies it is Titanium dioxide, TiO2 (Ti in IV state), not Titanium oxide.
Most likely, TFA should have referred to Titanium dioxide, as this is also a semiconductor in crystalline state.

Titanium oxide isn't used for pigments - titanium dioxide is.
One wonders how light stable this system will be compared to existing DVD coatings. My suspicions would suggest that it may be worse.
Buh. After reading about terrabit cube storage in 1994 http://bit.ly/cf4ufr [new scientist], I didn't upgrade my 3.5" floppies for years ... now I'm old, cynical about every article like this and my removable storage devices don't go past 32GB.
Come to Australia so we can strip search you and rob you of your internets, pr0n, rights and freedoms.
The point.
Why again do we need another slow optical disc medium? The times of those are clearly over.
Until that thing comes out, USB sticks are going to be 25 TB too. And much smaller. And not prone to scratching, sunlight, bending, dust, etc. And for everything else there is HDDs/SSDs.
Any sufficiently advanced intelligence is indistinguishable from stupidity.
Of all the conspiracy theories this one confuses me the most.
It displays a fundamental lack of understanding in both physics and meteorology. High altitude chemical spray is quite simply the the worst possible, if not impossible, way to disperse fluids. First off the winds aloft are different at 3K feet. At 10K-30K they are significantly stronger and can be in a different direction than on the group. Plus there the problem that the fluid would likely evaporate before reaching the ground. Another problem is that you couldn't fit enough "product" on a plane to cover any significant area.
Also the infrastructure required to perform "chemtrails" is insane. It would require the cooperation of at least the following groups of people.
Aircraft design companies
Aircraft manufacturing companies
FAA
Pilots
Airline companies
Airport ground crews
Chemical design engineers
Chemical manufacturing companies
Delivery companies
Yet somehow all these diverse groups can work together with no leaks or mistakes. I guess what amazes me most is the super human abilities attributed to the government.
we could just hire people to come and act out the movie for us.
It will never work out. The special effects explosions in action movies are hell on the furniture.
Worse still were the neighbors complaints after the snow scenes
My dear sirs. If I may raise a point in favour of this new technology:
Porn.
That will be all.
Obviously the government couldn't be behind it, but What about the Boy Sprouts or the Gnomes of Zurich?
