During the Innovating to Fuel the Next Decade of Big Data conference, Western Digital (WD) unveiled its findings on using Microwave-Assisted Magnetic Recording (MAMR) to deliver ultra-high capacity storage.

MAMR is an energy-assisted technology that uses an energy source to help write more data over an ultra-high density magnetic media.

“Our ground-breaking advancement in MAMR technology will enable Western Digital to address the future of high capacity storage by redefining the density potential of Hard Disk Drives (HDD) and introduce a new class of highly reliable, ‘ultra-high capacity’ drives. We have a proven track record for identifying, investing in and delivering advanced technologies that create new product categories and enable the world to realize the possibilities of data,” said Mike Cordano, President, Chief Operating Officer, Western Digital.

During the event, WD elaborated on MAMR technology, which demonstrates its reliability and ideal use for data center operations. WD’s MAMR technology utilizes spin torque oscillator (STO) to improve the ability to record data at ultra-high density without reliability problems. By using MAMR, it is possible to create hard drives with capacities of 40TB and beyond by 2025.

“Western Digital’s demonstration of MAMR technology is a significant breakthrough for the hard disk drive industry. Commercialization of MAMR technology will pave the way to higher recording densities, and lower cost per terabyte hard disk drives for enterprise datacenters, video surveillance systems, and consumer NAS products," said John Rydning, Research Vice President, Hard Disk Drives, IDC.

Previously, WD was developing another energy-assisted storage technology that uses heat: Heat-Assisted Magnetic Recording (HAMR). Unlike MAMR, HAMR technology faced reliability challenges that slowed down its development to be commercially viable.

While the theory of MAMR has been known within the storage industry for many years, WD was able to come up with a manufacturable and cost-effective plan that takes advantage of the new technology.
