How do hard drives work?

Nowadays they can easily hold more information than any library, and their capacity is still increasing. But how do they store such huge amounts of data? In this TED-Ed video, Kanawat Senanan explains how these powerful tools were created.

if you are going to purchase a laptop for this course or something else my advice is to go with the one having SSD as it makes your computers upto 10 times faster than having a HDD one.
