A Terabyte of Data on a Laptop Hard Drive

KaosConMan writes: "TechnologyReview.com has an article describing a new technique being developed by General Electric and IBM to further decrease the size needed to magnetically store data. This new technique could produce 150 gigabits per square centimeter-- that's ~57,000 songs on an iPod or a terabyte on a laptop size hard drive!"

AC thus spoke:

This is already obsolete. Terabytes of information on a creditcard sized medium have been announced years ago.

And it was replied:

Along with anti-gravity, ways to earn infinate money, and the secret of eternal youth.

The only difference is that this announcement comes from an actual lab with people who have actual degrees.

Security implications?

The article states that the new technology will only use one magnetic grain per bit as opposed to the hundreds currently used.

I wonder if this means that once a cluster is overwritten, there is no ghosting effect that could allow the previous data to be retrieved. Once the data's gone, it's gone. A single magnetic grain can only be set one way!

So NSA or whoever won't be able to retrieve those docs you wiped just before they busted into your home/office....

In the light of this, this tech. it is probably not in the security industry's best interest!

So as well as getting space for all your music and porn, you don't have to worry about the data persisting on your drive when you want to remove it... all in all a good thing!
