PetManimal writes "Techworld reports that Seagate has just patented something called 'Heat-Assisted Magnetic Recording,' which features nanotechnology and could lead to a 1.46TB 2.5-in. drive. The article says 'Storing data properly in extremely small areas requires the magnetic material to be heated during the writing phase, but this causes the lubricant film deposited on top of the magnetized recording layer to evaporate. Seagate's patent resolves this problem by having a reservoir inside the disk casing that contains nanotube-based lubricant. Some of this is periodically pumped out as a vapor and deposited on the surface of the disk, replenishing the evaporated lubricant.'"
