SDK has started supplying its 3.5-inch aluminum-substrate HD media for this application, using the eighth-generation 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, influencing their storage capacity.
