I get that in vinyl records, music is engraved into the disk; when a pin is run through the grooves, vibration occurs at the same frequency and wavelengths of the music and music is reproduced.
But how is data stored in plastic cd, disket, and USB?
Is it something like water memory? Metal memory? Plastic memories?
Thanks! Hope this post doesn’t get banned because I really wanna know!

While it seems you got a good intro to binary the actual process of recording these zeros and ones is cool.
For usbs and other solid state memory there are these electrical components called float gate transistors. The name isn’t important, the main thing is that these electrical components can take and discharge a charge and then hold that states for a long long time without being powered.
This is what makes USBs and solid state hard drives so fast. It’s all electricity and no moving components. Where as a CD or a Hard Drive has a physical. This disk needs to spin to read it all. That’s lame and slow.
