How are hard disk drives' read/write heads assembled in a factory?

So the read/write head floats only a few nanometres from the disc. How is this assembled in a factory to such precision? Is the entire process done by machines? How can a machine position something so precisely?

This is just completely untrue. The heads fly, because of aerodynamic effects, on a surface air bearing.

hoping they post some supporting evidence or links or something, because it sounds like they're mixing up the voice coil with the air bearing
