Which component stores magnetic data on a hard drive?

Explanation:
Magnetic data is stored on the physical surface of the disk’s platters. Each platter is coated with magnetic material, and tiny magnetic regions are oriented to encode bits. The read/write heads magnetize or sense these regions as the platters spin, allowing data to be stored and retrieved. The other terms—sectors, clusters, and slack space—refer to how data is organized logically and allocated by the file system, not the physical storage medium itself. Hence, the platter is the component that stores magnetic data.
