   How does a hard drive work?

   • Inside every hard drive are small round disk-like objects made of either an aluminium/alloy or a glass/ceramic composite, these are called platters, each platter is coated with a special magnetic coating enabling them to store data magnetically. Hovering above these platters are read/write heads that transfer data to and from the platters.
