Demo of the inner working of a Hard Drive

When ever I get to take apart a gadget and look inside, I can't help but stare in wonder at its working. This is especially true when the said device consists of some moving parts. Sometimes I can't help thinking that we humans should pick up a thing or two from the gadgets - especially the team work bit. All the small pieces of the gadget come together and work as a single entity - each doing its own alloted work efficiently - thus acomplishing complex tasks.

Josua Marius has videoed the inside of a hard disk and demonstrates how the lever reacts when one modifies the data on the hard disk. The whole process looks really interesting.
