Seagate claims breakthrough in magnetic data storage - DQ CHANNELS INDIA

Seagate Technology has announced that its scientists have broken new ground in the field of magnetic data storage by demonstrating areal densities of over 100 gigabits per square inch (Gb/in2) using perpendicular recording technology.

"Perpendicular recording is projected to achieve areal densities as high as one terabit per square inch (Tb/in2), roughly 20 times the density of today's state-of-the-art disc drive products," said Dr Mark Kryder, Seagate Senior VP of Research.

"This is equivalent to storing over one full terabyte (1000 gigabytes) of information or nearly 500 DVD movies on a single 3-inch disc." Seagate anticipates implementing perpendicular recording within its products perhaps as early as calendar year

004. 

Seagate's performance demonstration showed perpendicular recording functioning at a record data rate of 125 Mbytes per second with an areal density of nearly 60 Gbits per square inch. This is the highest data rate and areal density combination ever reported for perpendicular recording, advancing the state of the art over the previous record of 125 Mbytes per second at only 13 Gbits per square inch.
