Nanotube Lube Replenishment for Massive Drives 144
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.'"

Perfluoropolyether is the lubricant. And it's not 'nanotube-based' at all. It's delivered via the tubes.
From the article: "Vapor PFPE also surrounds the platter. As the drive spins, areas of the platter will get hot, which will wear out the lubricant. The vapor PFPE deposits on the platter to replace the worn out lubricant. The "condensing" vapor lowers vapor pressure which then draws out lubricant from the CNTs until the pressure is equalized."
It does say the reservoir will provide ten years of 'practical' use. For someone who uses their hard drives a LOT (maybe someone without enough RAM?

In order for condensing vapour to lower the vapour pressure in a manageable way, the unit would need to be sealed. If it's sealed then why cant the initially vapourised lubricant be re-deposited and recycled?
PS - I know you can have local vapour pressure changes without a sealed environmant, but if the drive was ventilated as per normal then you'd get a nasty lubricant loss every time the drive heated and cooled (started and stopped) - the vapour would be pumped out of the vent hole.

As evidence, if you look at most hard drives you will see small vent holes (usually easily visible because of the warnings not to cover them).

Although, personally I think the future is in high-capacity flash-memory type storage.
