Self Lubricating Hard Drive
I don't want anyone passing smart-ass comments about the title of this post ok? I have to admit that anything related to lubricants could be associated with, uh, you know what, but this story has nothing to do with this. It seems that Seagate, in their infinite wisdom, came up with an innovative way to store several terabits of data per square inch into a disk, about 10 times as much as is currently possible, by using nanotube-housed fluid to lubricate a drive as it spins.
Apparently, a heated hard disc is capable of cramming more data into closer quarters, but the method hasn't been implemented in current drives since the heat evaporates the lubricant that allows the recording head to travel smoothly over the disc, causing a fatal disc crash. Seagate's new patent addresses the issue by storing lubricant in a special material made from millions of carbon nanotubes and embedded in the drive housing - source: Engadget.
