Toshiba Unveils World's First FC-MAMR HDD: 18 TB, Helium Filled
Toshiba this week announced the industry's first hard drive featuring flux-control microwave-assisted magnetic recording (FC-MAMR) technology. The new MG09-series HDDs are designed primarily for nearline and enterprise applications, they offer an 18 TB capacity along with an ultra-low idle power consumption.
The Toshiba MG09-series 3.5-inch 18 TB HDD are based on the company's 3rd generation nine-platter helium sealed platform that features 18 heads with a microwave-emitting component which changes magnetic coercivity of the platters before writing data. The HD disks are made by Showa Denko K.K. (SDK), a long-time partner of Toshiba. Each aluminum platter is about 0.635 mm thick, it features an areal density of around 1.5 Tb/inch2 and can store up to 2 TB of data. The MG09 family also includes a 16 TB model which presumably features a lower number of platters (based on the same performance rating).
