How does a tiny device hold more data than a library?

How do hard drives work? - Kanawat Senanan · 5:12 · Video: TED-Ed · Watch at the source

In short: This video explores the incredible engineering behind modern hard drives. Discover how generations of scientists and physicists collaborated to create a tool capable of storing vast amounts of information in a remarkably small space.

The development of the hard drive is a feat of multidisciplinary precision, involving contributions from engineers, material scientists, and quantum physicists. This evolution has transformed a small physical object into a powerful device that can store more information than an entire local library.
