Watch hard drives being made

Ever wonder how today’s hard drives are manufactured?  I think it’s amazing that we can buy hard drives that store more than a terabyte for about a hundred dollars. When you watch this video, you’ll see how this miracle in manufacture is done.

All operations are performed in a clean room environment, because clearances and tolerances are measured in fractions of microns. (A micron is about 0.00004 inch. A human hair ranges from about 20 to 150 microns in diameter.)  In operation, the read/write head of a modern hard drive flies a few nanometers above the platter surface.  A fingerprint on a platter could cause a head crash.
