The engineering marvel that is your HDD.
Today we may be all about solid state flash memory for our storage needs, but there's a high chance that the majority of our data still resides on magnetic-based disk drives.
In fact, we've relied on hard disk drives and its magnetic genius to store our data for decades. Without storage, our computing experiences would be meaningless, like going through life unable to remember what you experienced just a second ago.
Bill Hammock, the "EngineerGuy", has created a new video in his YouTube series, and this one explains just how hard disk drives work. They're quite amazing pieces of engineering, even in today's world where SSDs are the new bleeding edge storage medium.
Check it out below:

No it's giggitygiggitywatts
I learned a few new things from it as well

If we get a flux capacitor maybe it might need that
according to
3.6*(15000/60)*2*pi*(2.5*2.54/2)/100/1.609
their speed is up to 111 mph or 180 km/h.
You know that referance to Jiggowatts in that movie was supposed to be Gigawatts but they didn't know how to pronounce it. It's not some special unit of electricity its the Giga abrevation (same as gigabits or gigabytes) they just didn't pronounce correctly.
Pretty sure that's the joke...
lies! its jiggyjiggywatts!

LOL!!!!!!! Oh man, it's flashback time! Heh.
The guy did a good job explaining it.
I now have a better understanding of Hard Drives.
The inductive read element has been discarded in the 90s and the longitudinal media shown was replaced by 2006.
Also PRML channels are long gone, actually they originally were created to boost phone line mode performance in the late eighties.
Modern actuators combine VCM and piezzo technologies.
Recent head technology actively manages fly height via thermal profile control.
It's time for an update.
