    • Quickly rotating platters coated with magnetic material

      • An HDD stores data on quickly rotating platters coated with magnetic material. Read/write heads on actuator arms scan over the platters, magnetizing or sensing the magnetization of the material to read or write data. The platters spin at high speeds, allowing the heads to access data anywhere on the disks within milliseconds.
