Showa Denko K.K. (SDK) has started commercial shipments of 2.5-inch hard disk (HD) media with storage capacity of 500 gigabytes per disk, using the sixth-generation perpendicular magnetic recording (PMR) technology.
To the best of our knowledge, our new 2.5-inch HD media have the world¡Çs highest storage capacity for this size available on the market today. SDK has already commercialized 1.89-, 2.5-, and 3.5-inch fifth-generation PMR media.
Demand for high-capacity HD media is growing for such applications as PCs, cloud computing and digital electric appliances. To ensure speedy and stable deliveries of best-quality high-capacity HD media, SDK completed capacity expansion at its site in Singapore in June this year.
As a result, SDK¡Çs total HD media production capacity has been increased to 27 million units a month since July this year. SDK is developing world-leading technologies for HD media with higher capacity. As the world¡Çs largest independent HD media supplier, SDK will continue meeting customer requirements in terms of quality as well as quantity.
