What is the circular disk on which magnetic data is stored in a hard disk drive called?

Explanation:
The circular disk on which magnetic data is stored is called a platter. In hard disk drives, data is written magnetically to the surface of each platter, and drives can have multiple platters stacked on a spindle. Read/write heads glide over these surfaces as the platters spin, reading or writing data organized into tracks and sectors. Slack Space refers to unused space within a file allocation unit, Sectors are the smallest addressable units on the disk, and Garbage Collection is a process associated with reclaiming space in flash memory. The term platter specifically names the physical circular disk that stores the data.
