TOKYO, Dec 11, 2015 - (JCN Newswire) - Showa Denko (SDK) (TOKYO:4004) announces that its HD media have been adopted in helium-filled 10 terabyte hard disk drives (HDDs), which represent the world's highest storage capacity. [Note 1]
SDK has started supplying its 3.5-inch aluminum-substrate HD media for this application, using the eighth-generation perpendicular magnetic recording (PMR) technology. [Note 2] In 2005, SDK became the world's first to manufacture and sell PMR-technology-based HD media.
HDDs are widely used for recording digital data. Despite gradual decline in demand for PC applications, HDDs are now increasingly used in data centers, reflecting exponential growth in data in line with the progress of cloud computing. Compared with unsealed PMR HDDs, helium-filled HDDs help reduce power consumption. Thus, helium-filled HDDs will be used more and more in data centers, which are increasing in number.
As the world's largest independent HD media supplier with a market share of about 25%, SDK has been speedily launching highest-level-capacity HD media. HD media are key components of HDDs, significantly influencing their storage capacity. SDK will continue to strengthen its HD media business in accordance with the company's motto of "Best in Class."
