The company Showa Denko K. K., the largest independent manufacturer of magnetic plates for hard drives (hard disk drives, HDDs), confirmed plans to begin mass production of plates with perpendicular magnetic recording (perpendicular magnetic recording, PMR) ninth generation next year. These carriers significantly increase the capacity of hard drives for mobile and desktop, and servers.
In March, Showa Denko K. K. (SDK) IMPORTED PMR-eighth generation capacity plate 750 GB 2.5-inch hard drives. A little later, the company launched a PMR-carriers eighth-generation 3.5-inch HDD. This month Showa Denko told, what is it used in the plate recently submitted 10-TB hard drives HGST Ultrastar He10, which are filled with helium and capacity using seven plates 1,43 TB each.
The ninth-generation PMR-plates SDK will increase the capacity of media for 2.5 inch HDD to 1 Tbayt (or to 1,3 Tbit per square inch), which will produce drives for high capacity mobile computing. Since the wafer using conventional technologies perpendicular magnetic recording, from hard drives based on such carriers should expect better performance as the operations of reading, and the operation record.
Subsequently, the ninth generation PMR technology will increase the capacity of magnetic plates for 3.5-inch hard drives to 1.5-1.7 terabytes in 2016 1,7-2 year to TB in 2017 p. So, manufacturers of hard drives, that have the technical ability to produce helium-filled hard drives with increased number plates - HGST, Seagate - will present over capacity HDD 10 TB in 2016 and 2017 years. Manufacturers, not using helium within their drives - Toshiba, WD, - also can increase their capacity HDD.
With regard to further increase the capacity plate and hard drive, that Showa Denko - like other market participants, high hopes for thermomagnetic recording technology (heat-assisted magnetic recording), which will increase the recording density to 1.5-2 Tbit per square inch in the near future.
