Toshiba Claims Data Storage Breakthrough
Toshiba says it has achieved a breakthrough in data storage technology that could lead to hard drives with much higher capacities than are currently available.
Toshiba says it has developed prototype bit-patterned, magnetic-storage technology that is built at a density equivalent to 2.5 terabits per square inch. The storage capacity is five times greater than Toshiba's current highest-capacity drive, which has a density of 541 gigabytes.
Bit-patterned media breaks up the recording surface into numerous magnetic bits, each consisting of a few magnetic grains. Toshiba's scientists say they have produced a media sample in which the magnetic bits are organized into a pattern of rows, which act as markers to where data is stored. Toshiba says the first commercial bit-patterned drives should be available in about three years.
