Computer hard-drive seeking demonstration

http://video_demos.colostate.edu

Demonstration of the components and operation of a computer hard-drive. The drive has a transparent cover so the internal workings can be seen.

Many more video demonstrations of engineering and physics principles and devices can be found at:

"as you can see, its too fast for you to see" hehehhe.

cool tho. thanks for sharing

I hadn't noticed the "as you can see" comment before ... that is funny.

That arm must be incredibly light, strong and rigid to withstand the acceleration forces without deforming.

[DrDaveBilliards]

Strength isn't as much a concern as lightness and stiffness (i.e., the strength part is easy). But you're right ... the arm is designed to be as light and stiff as possible.

All hard drives should come with clear covers...

[DrDaveBilliards]

Agreed. All computers should have transparent cases also. :)

Utterly increadible, especially when you think that a HD that costs £30 can operate like this with outstanding accuracy for years on end.

That's a cool video. You realise how quickly the read / write head + arm is moving. I guess the tolerances are quite high in order for the hard drives read / write head + arm can move by using ground air effect ?

@arunarun4 Watching a recorded video isn't "real-time". ;-)

[Atheismrulez]

Geek porn right here.

@DrDaveBilliards as far as i know, you can get a clear case from somewhere like aria, dabs, or one of the known or not so known manufacturors and and i think i saw one of the known HDD manufacturors do a HDD with part of it see-thru...

[ratsmart9]

Were would you find such a hard drive?

i do want a HDD with that transparent cover :D
