How a Hard Disk Drive Works

Check out the latest video on the technology inside a hard drive.

Seagate engineer demonstrates how a hard disk drive works

To people who continuously ask, how can someone invent all of this.
This is not merely work on one individual person,
Engineering is a field that builds on top of previously uncovered knowledge.
This is work of hundreds of individuals who have made contributions over centuries and centuries, through their work in Mathematics, or Physics, or any other discipline related to those two.
The knowledge acquired by individuals over centuries has allowed us to build everything you see around you today.
This wasn't invented in a single day.
But, regardless, it's still amazing how the knowledge is understood and applied by Engineers to build these machines.

feels like I watching a 90s documentary with that music. kinda digging it too

[KingTaterthot]

She's pretty good at explaining something so complex.

[jayyoutube]

Amazing someone could engineer such a device..

4:35 That's the keyboard of someone who understands stuff quite a bit

[murdoch]

The concept of anything being just a few atoms thick amazes me. Such a feat of engineering and to consider this type of technology started way back in the 1950s.

Doing a research project on HDDs. Learned how one of the founders of the company (Shugart) used to work for IBM and was tasked with consolidating data stored on thousands of punch cards. The data on the punch cards was essentially the 1s and 0s explained in the video. So insane how after so much advancement in the technology, the fundamental step of reading 1s and 0s (true/false, north/south) is what governs the whole mechanism's structure.

I understood some of those words. 10/10

That's high tech, very precise piece of art and technology

*Main components:*
Case
Platters
Actuator
Printed Circuit Board

*Other components:*
R/W Heads
Spindle Motor
Actuator magnets
Heads Ramp

*Hard Drive's main role:*
To store all the data, in this case: as magnetic regions and bits on the platters that are coated with a magnetic film.

Finally, a very understandable beginner level introduction that I can lean about the HDD technology. I am not in IT field, this video helps me to understand the principle of a HDD.

Thank you very much.

Incredible technology! It's hard to believe that this head can move so extremly precisely at a huge speed. Wow.

Why those people disliked this video! What were actually they expecting from here?

[georgederisse]

Very useful informations. You have not only the knowledge but the ability to explain every details of the process. I learn a lot from your video and I will follow you. Thanks to Seagate and the engineer.

[สมชายสุขมาก]

Very good video. I have ever worked with Seagate from 1994 to 2001. In Thailand. Seagate is Very good company.

Just think this will be considered old technology in a few years with SSDs becoming the norm. Such an amazing feat of engineering .

[warpspeedpower]

Excellent explanation, especially for newbies wondering how these things work. There's a lot of science that goes into this. The only downside is that Seagate do not put as much effort into quality control and quality parts as Western Digital. WD have far less defective drives, and drives that break prematurely. Which is why their warranties tend to be longer and their drives more expensive.

How can we be so precise? How can we create a magnet which is as big as a atom? How can we create a gap which is as big as an atom? All the people who have worked on these over these last 50-100 years, I am just impressed. Fair play

[ruanjiayang]

It is just amazing that such a delicate and accurate machine is right under my hands.
