Showa Denko K.K. (SDK) has started commercial production of perpendicular-magnetic-recording-technology-based hard disk (HD) media.

Demand for HD media is growing rapidly for mobile devices, PDAS, DVD recorders and mobile music players. To be able to handle sounds and moving pictures, these applications require higher storage capacity of HD media.

Compared with the conventional technology that stores magnetic data on a horizontal plane of the HD media, the latest technology of SDK enables vertical magnetic recording. It enables a dramatic increase in recording density, at a time when the conventional technology is now reaching its limit of raising recording density, the company said.

SDK has started commercial production of 1.89-inch-diameter media for use in mobile music players, having the capacity of 40 gigabytes per disk--double the capacity of conventional products of the same size. While the company earlier announced that it will increase its HD media production capacity by 3.05 million disks per month to 13.75 million disks per month by March 2006, all of the new production lines will be able to use the perpendicular magnetic recording technology.

SDK has also started commercial production of the industry's smallest 0.85-inch diameter HD media. Very-small-diameter HD media, including the 0.85-inch type, will soon be installed in cellular phones to enable handling of music and TV programs transmitted via Internet. Thus demand for very-small-diameter HD media is expected to grow at an annual rate of 30 percent.

At present, the company is actively investing in its HD media business, classifying it as one of the strategic growth businesses.
