What is the structure of a disk?
The structure of a disk, also known as a hard disk drive (HDD), consists of several key components. At its core, a disk is composed of one or more magnetically coated platters that spin at high speeds. These platters are layered on a spindle and are read and written to by an actuator arm with attached read/write heads. The platters are divided into tracks, which in turn are divided into sectors. Each sector can store a fixed amount of data. The disk is controlled by a printed circuit board that manages data transfer, motor control, and other functions. Additionally, there is often a reserved space on the disk called the file system, which keeps track of the location and organization of files stored on the disk. Overall, the structure of a disk is intricate and precise, allowing for efficient data storage and retrieval.
