A breakthrough will allow Western Digital to create 40 TB hard drives

Western Digital, with several purchases that have made in recent times as the company HGST, has continued to innovate as much as possible in a sector that is seen as stagnant and traditional as the hard disk. However, the company has shown that much remains to be researched and done. And now announcing a technology that will allow the creation of hard drives up to 40TB.

40 TB A reality?

A breakthrough will allow Western Digital to create 40 TB hard drives

MAMR Technology?

The technology is called microwave assisted magnetic recording (MAMR). Its operation has a base on helping the head. That is moving the plates of the hard disk with microwaves. So, making the magnetic moment of an oscillator of spin used to record can increase the density of information. That can be engraved on the plate. Current heat-assisted recording technology (HAMR) will reach its 20 TB limit around 2019 or 2020, while the MAMR will continue to grow to reach 40 TB by 2025.

MAMR technology is the latest result in a series of HDD innovation for the company. Recently the company released the first 14TB, helium, SMR drive. However, a key to MAMR is WD’s micro-actuation and recording head manufacturing technologies. According to WD, this technology enables hard drives to accurately and reliably position magnetic heads for writing and reading at ultra-high densities.

The company also leverages Damascene processing, allowing for it to manufacture heads with the precise tolerances. And complex structures required for reliable and cost-effective recording at ultra-high densities. And provide the capability to embed the spin torque oscillator that enables the manufacturing of MAMR heads.

Availability

Western Digital expects to begin shipping ultra-high capacity MAMR HDDs in 2019.

 

MAMR will initially be used for enterprise-oriented and data center hard disks. And will initially arrive in 2019. The development of area density will increase by around 15% per year after that.
