Hitachi and Seagate and others unexpectedly collaborate in "next generation recording technology" research to increase HDD recording capacity

In February 2009, 2 TB model 3.5 inch HDD began selling in JapanAlthough it has not been updated the maximum capacity of HDD, since it became clear that Hitachi and Seagate, major HDD makers, will collaborate extensively on research on "Next Generation Recording Technology" that will increase HDD recording capacity It was.

It is unusual for such affiliation to be done, but as research progresses through tie-ups, it may be that clues to larger capacity HDDs will be visible.

Details are as below.
Hitachi and other HDD top three companies tie up with next-generation recording technology: Nikkan Kogyo Shimbun

According to the Nikkan Kogyo Shimbun news report, Hitachi Global Storage Technologies (HGST), Seagate and Western Digital, the top HDD manufacturers in the world share, are tying up to research and develop next-generation recording technologies.

The physical limits hindered large capacity, such as confronting the problem of "thermal fluctuation" which makes it impossible to store data stably as the recording density of the conventional HDD increased. However, "One bit can be recorded per magnetic particle"Patterned media"Writing magnetic data while applying heat by applying light to minute areas of the disc"Thermally assisted magnetic recording methodWe share the development roadmap such as "We will cooperate in standardization etc.

In addition, although it is necessary to invest a huge amount of money to commercialize the HDD adopting the next generation recording technology, this tie-up can be aimed at cost reduction, and from now on HDD manufacturer Toshiba and Samsung, Fuji handling recording medium It is said to encourage participation in TI and Marvell Technology of electric machinery and semiconductor companies.
