Western Digital Corp., one of the world’s largest makers of hard disk drives, this week demonstrated the world’s first hard drive with heat assisted magnetic recording (HAMR) technology at the International Forum on Advanced Materials and Commercialization. The new recording technology will eventually enable higher-capacity hard disk drives.

“Analysts predict 25 trillion gigabytes of new data will be generated by 2020 and that average household storage needs in the U.S. will require as much as 3.3TB by 2016. This tremendous growth in data requires continued increases in storage capacity and performance for the cloud, big data and consumer technologies. WD is focused on hard drive innovations that will enable future storage capabilities, and HAMR technology is a key step in the migration path,” said William Cain, vice president of technology at WD.

Western Digital did not release a lot of details regarding the actual hard drive featuring a platter based on HAMR technology, but demonstrated a fully-functional notebook PC running the drive, which means that the hard disk drive platform is ready.

HAMR technology may offer a solution for increasing areal density (AD) by magnetically recording data on high-stability media using laser thermal assistance. The technology shrinks data bits in a stable manner by briefly heating the disk surface during magnetic head recording. The method can increase data density by a factor of more than 5 and ultimately results in storage capacities as great as 4 terabits per square inch.

WD is addressing the challenges associated with HAMR technology, including designing media that manages the increasing complexities of concurrently meeting magnetic, thermal and optical requirements; laser light path integration; and head-disk interface reliability and lifetime.

Since they apparently did not even quote the capacity of the platter (or HDD), I think it is premature to announce "the hard disk drive platform is ready".

right, thought about the same thing. There is just a line where it says how much this new technique can improve capacity but not how much it does already. Also I wanna see this tech profe (or prove?, sorry english isn't my mothers tongue) in server environment, to see if its stable and secure... If we finally get 20 TB Disks, I don't wanna lose 20 TB of Data left and right.
Making a RAID is not the problem, but moving back 20 TB to a new Disk if one in a Raid 1 Mirror breaks down, is just a pain...

The technology has been ready for quite a while, but they are not releasing it because there is absolutely no competition on the hard drive market. They don't need to release anything new.

I have three 1 TB drives bought for less than 60 $ a piece and now, three years later, they are 50% more expensive. That's because of the F***ing duopoly we now have on the HDD market.

I thought heat destroys magnetism?...:/

Too much heat detroys magnetism, but just the right amout, for the right duration, allows a much smaller area to be magnetized, as well as erased, without also erasing neighboring bits, on the same and other tracks! Having more space per drive is great for NAS raid devices, where redundency takes up a lot of space, but on laptops having multi-terabyte hard drives, will need a low cost super fast expansion technology, in order to back up the drives while not taking up the user's whole day! I would rather see 1.5 tarabyte super thin drives in laptops stacked in a raid configuration of 2 hard drives(raid #) with the os on a 3rd SSD, and each HD with a good amount of Cache memory (Flash/RAM).

"average household storage needs in the U.S. will require as much as 3.3TB by 2016."

Guess I'm not average... I just ran out of space in 10TB I have in one computer alone...
