With tech breakthrough, Seagate promises 60TB drives this decade

With tech breakthrough, Seagate promises 60TB drives this decade.  Lucas Mearian. Computerworld.  March 20, 2012.

 Seagate said they have achieved a density of 1 terabit (1 trillion bits) per square inch on a disk drive platter. The technology would lead to the production this decade of 3.5-in. hard drives with up to 60TB of capacity.

As drive manufacturers store more bits per square inch on the surface of a disk, they also tighten the data tracks. The challenge as those tracks tighten is overcoming magnetic disruption between the bits of data, which causes bits to flip their magnetic poles resulting in data errors.
