Bangalore: Seagate has become the first hard drive maker to achieve the 1 TB (terabit) per square inch milestone. The company demonstrated the technology that promises to double the today’s storage capacity and give rise to 3.5 inch hard drive with an extraordinary capacity up to 60 TB.
Seagate reached this landmark with the next generation recording technology called Heat-Assisted Magnetic Recording (HAMR). Currently the hard drives uses the Perpendicular Magnetic Recording technology (PMR) which has spinning platters inside every hard drive to record the spectrum of digitized data like music, photos, videos and files on desktop and laptop.
“The growth of social media, search engines, cloud computing, rich media and other data-hungry applications continues to stoke demand for ever greater storage capacity,” said Mark Re, Senior VP of Heads and Media Research and Development at Seagate. “Hard disk drive innovations like HAMR will be a key enabler of the development of even more data-intense applications in the future, extending the ways businesses and consumers worldwide use, manage and store digital content.”
Hard drive manufactures are increasing the areal density and capacity by shrinking a platter’s data bits to pack more within each square inch of disk space. The maximum capacity of today’s 3.5 inch hard drive is about 620 gigabits per square inch. Using the HAMR technology Seagate can produce up to 1 terabit of capacity per square inch in 3.5 inch hard disk in near future.
