DISK DRIVE

Disk drive is a machine that reads data from and write onto a disk. Disk drive rotates the disk with precise timing and has one or more read/write heads that read  and write  data. The data is read by the read/write head and  transferred to the computer's  main memory for further processing. There are different types  of disk drives  for different types of disks e.g. a hard disk drive (HDD) reads and writes hard disks, and  a floppy disk drive (FDD) accesses  floppy disks, and an optical disk drive reads  optical disk. Disk drive can be either internal ( house within the computer) or external (house in a separate box that connects to the computer.
