TDK to Double Hard Drive Capacity with Frickin' Lasers

Outside of Hollywood, lasers mounted on sharks is a technology that may never be realized. But in hard drives? The mad scientists at TDK on working on this very thing, and once completed, it has the potential to more than double the capacity of today's hard drives. This isn't a theoretical technology that's still years or decades away, but one that will manifest in shipping drives by late next year, according to reports.

The mechanical hard drive sitting in your rig at home utilizes rotating platters. In order to read and write data to and from the platters, a magnetic head gets as close as it can with crashing into them. It's pretty remarkable when you get into the science of it all, but also pretty limited. It gets increasingly difficult for platters to hold proper magnetic charges as more data is packed onto the platters, and that's going to be a problem moving forward.

Today's mechanical hard drives use magnetic heads to read and write data.

TDK's solution is to use lasers in conjunction with a high coercivity material that's stable at normal temperatures but has to be heated when writing data. The technology is called heat-assisted magnetic recording (HAMR). Using this new technology, TDK expects to able to build a 2.5-inch hard drive with 1TB platters. In the 3.5-inch space, this could translate to 8TB hard drives (four 4TB platters).

Cool... I wonder how they read data as well as whether or not they're as suspectable to stuff such as magnetic interference... Also when will this stuff hit the shelves? Doesn't matter, we can look at the images and just imagine us having 8TB hard drives in our possession. I admit that TDK did have a bit of a brand reputation when it came to the products they made but if this is released and it doesn't have any crippling bugs in it then TDK can officially be redeemed.

This sounds good to me too. As long as they don't price it up into the stratosphere it will be good technology.

This sounds like it can solve a lot of problems associated with mechanical failures in hard drives too making our data not only more copious but safe and reliable as well...

This sounds like something that if TDK can pull off that all the Major Hard Drive manufacturers will pick up...

Just wait will there's a Hybrid Laser-Platter/SSD Drive, that things gonna be amazing

Seems really fantastic with the new tech.and pretty sure that TDK will be successful moving forward with this...didn't we  have some 'brain cloud 'idea a while back with some parallel HD platters Neil ? this look like the vision to me .even though the tech behind it was not apparent till today .

maybe it just a bad case of my Sunday night math or something but "(four 4TB platters)" would not translate into a 8TB drive ? I apologize for any of my error in advance.

Yeah, the Math is a little ~off sounding~ unless there's a Chinese translation that I'm not aware of. But I never noticed it the first time that I read it.

yeah Neil I looked at it too   but was that you when we had some article and maybe we were thinking a bout some parallel platters on the mech HDs like we are seeing here   surely this is no small feat in tech and manufacturing  but maybe thinking that this type of tech was a of a stretch down the road and now seems 'round the corner .

Nice... would heating the platters up not cause an issue by warping them. I could see this as a really cool technology. I hope they succeed with making a quality product.

TDK has been around for quite awhile. It makes sense to me for them to be getting in to the hard drive business, or maybe they have been, and just haven't heard. They used to have a large presence in the magnetic cassette tape market, so this isn't that far fetched.

Can only imagine this will be good for the hard disk business as the accuracy of lasers should allow for increases in speed.

As far as the math goes, I think what they meant was 1TB per side. So 4 platters= 8TB.
