SDK Shipping 2.5-Inch 334GB Hard Disk Media

Showa Denko K.K. (SDK) has started commercial shipments of 2.5-inch hard disk (HD) media with storage capacity of 334 gigabytes per disk, using the fifth-generation perpendicular magnetic recording (PMR) technology.

To the best of our knowledge, our new 2.5-inch HD media have the world’s highest storage capacity for this size available on the market today. SDK has already commercialized 1.89-, 2.5-, and 3.5-inch fourth-generation PMR media.

Demand for high-capacity HD media is growing for such applications as PCs that enable storage/editing of moving pictures as well as HDD recorders that can record high-definition TV programs. SDK has established a setup for ensuring speedy and stable deliveries of best-quality, high-capacity HD media based on the PMR technology. SDK is making preparations for timely commercialization of its fifth-generation PMR media in other sizes.

SDK is developing world-leading technologies for HD media with higher capacity. As the world’s largest independent HD media supplier, SDK will continue meeting customer requirements in terms of quality as well as quantity.
