FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.

Detailed explanation-2: -A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.

Detailed explanation-3: -A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

Detailed explanation-4: -They store data in the form of magnetized spots in adjacent circular tracks on the surface of a metal cylinder. A single drum may carry from one to 200 tracks. Data are recorded and read by heads positioned near the surface of the drum as the drum rotates at about 3, 000 revolutions per minute.

Detailed explanation-5: -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.
