Detailed explanation-1: -A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors. Hard disks, zip disks and floppy disks are common examples of magnetic disks.
Detailed explanation-2: -Hard-disk drives represent the most widely used form of magnetic storage in use today. A hard-disk drive consists of a rigid disc made with non-magnetic material, which is coated with a thin layer of magnetic material. Data is stored by magnetizing this thin film.
Detailed explanation-3: -hard disk, also called hard disk drive or hard drive, magnetic storage medium for a computer. Hard disks are flat circular plates made of aluminum or glass and coated with a magnetic material. Hard disks for personal computers can store terabytes (trillions of bytes) of information.
