If everything goes according to plan, in the next ten years Seagate will launch on sale hard disks (HDD) with a capacity of 100 terabytes, which is more than five times the current figures for the largest HDD, but after 2030 technology is likely to surpass the 120 terabytes…
The bulk of Seagate’s efforts are focused on developing thermomagnetic recording technology (HAMR).
A Seagate spokesperson explained:
“HAMR is a direction that allows us to make a new leap in the amount of information stored on a hard disk. It uses a new kind of magnetic technology on each disk, which makes it possible for particles or grains of information to become smaller and more densely compressed, while maintaining magnetic stability. A small laser diode attached to each recording head heats up a tiny area on the disc, allowing the recording head to reverse the polarity of each stable bit, thus enabling information to be recorded. “
Seagate recently emphasized the need to move away from traditional perpendicular magnetic recording (PMR) to move forward more actively.
“With the help of PMR, we were able to increase the capacity of hard drives by 1 or 2 terabytes each time,” he noted. Jeff Fochtman, VP of Business and Marketing, Seagate.
“With HAMR technology, we can jump straight to 4 terabytes, 6 terabytes, or even 10 terabytes with every new disk.”
Despite the emergence of SSDs on the market, HDDs remain a reliable and cheaper choice for storing large amounts of information. The demand for hard drives is not falling.
