Seagate's latest hard drive has hit a milestone: it manages to squeeze in a data density of one terabit per square inch. It uses some extremely complex heat-assisted magnetic recording to do that, and in the process doubles the storage capacity of current hard disks. If that's not enough to get your head round, how about this: the hard disk contains more bits in a single square inch than the Milky Way has stars. [SeagateImage credit: sar_38/Shutterstock]
