Seagate Demos Leap in Storage Density

FRAMINGHAM (03/23/2000) - Technologists are now able to store 45 billions bits of data in a square inch of space on a storage device, the highest so far.

Today's announcement by Seagate Technology Inc. in Scotts Valley, California, was based on a demonstration by Seagate researchers.

The lead in the race to increase storage density is sometimes swapped with IBM Corp., but Seagate boasted that its latest announcement doubles its previous density record and is the third world record it has hit in a year.

The furious discovery pace for storage density is driven by seemingly insatiable demand, as more computers and devices are connected to the Internet and demand compact storage devices to operate. Enterprises are especially concerned about controlling the amount of floor space devoted to storage devices, making the more-bits-per-square-inch improvements important.

John Monroe, a storage analyst at Dataquest, a division of Gartner Group Inc. in Stamford, Conn., said networked systems sometimes require 30 million transactions in a given moment, all depending on computers accessing stored data.

Seagate said the demonstration means 60GB of data can be stored on a single 3.5-in. disk, enabling a home user to store up to 25 DVD -quality or 50 VHS-quality full-length movies on a compact two-disc personal video recorder.

Seagate said the innovation is possible because of improvements in recording heads and a multilayer proprietary Seagate film media applied to disks that can handle heat and prevent data corruption.
