Showa Denko K.K. (SDK) has started commercial shipments of 1.3-inch hard disk (HD) media with storage capacity of 40 gigabytes per disk, using the perpendicular magnetic recording (PMR) technology.

The media are to be installed in hard disk drives (HDDs) as small in size as Compact Flash Type.

SDK believes that 1.3-inch-media-containing HDDs will provide larger storage capacity at lower costs compared with Compact Flash memory cards, and ensure lower electricity consumption and higher resistance to shock than 1.89-inch-media-containing HDDs. "Demand for the new 1.3-inch PMR-technology-based HD media is expected to grow for such applications as high-definition camcorders, mobile music players and very small notebook PCs," the company said.

In June 2005, SDK became the world?s first company to use the PMR technology for commercial production of HD media, enabling a dramatic increase in recording density. SDK is already offering 1.89-, 2.5-, and 3.5-inch HD media based on the PMR technology, all having the world?s highest storage capacity for each category at this moment.
