Seagate Technology has unveiled its first 2.5-inch drive using perpendicular recording technology, and introduced nine other hard disk drive products for various markets, including storage, automotive and consumer.

The Momentus 5400.3 is a 160GB disk drive that delivers 5,400rpm performance with 25 percent more capacity than the largest notebook drive currently available, according to the company. It employs the next-generation storage technology, which arranges the magnetic bits vertically on end on the surface of the disk to allow the head to record and read more information per unit area.

Hard disk drives manufactured today use longitudinal recording that arranges the bits horizontally on the disk, which requires more surface area to store information.

"With the expansion of its product line both last year and this, Seagate has shown it is very agile at customizing its technology to fit even more unique and varied application needs," said Mark Geenan, president of market research firm TrendFOCUS. "By designing products for new markets based on specific customer needs, using its ability to leverage underlying technology platforms across markets, Seagate has pioneered a new way of thinking about and designing hard drives."

The company has also introduced automotive drives and what it claims is the industry's first 2.5-inch drive for DVRs and game consoles and 8GB drive for portable media players.

The EE24 series designed specifically for cars can operate in temperatures from -30C to 85C and in high-humidity and high altitudes. And the LD25 series features 2.5-inch drives for the latest game consoles.

It will provide up to 85 hours of HDTV recording, 500 hours of standard TV recording, and up to 10 simultaneous TV stream. DynaPlay technology fine-tunes the drive's operating parameters for entertainment applications.

The 8GB CompactFlash Photo hard drive will offer 8,000MB of capacity in a 1-inch size for digital cameras. It will be capable of storing 2,400 high-resolution and 6,400 standard-resolution digital photos.
