Detailed explanation-1: -A magnetic disk primarily consists of a rotating magnetic surface (called platter) and a mechanical arm that moves over it. Together, they form a “comb”. The mechanical arm is used to read from and write to the disk. The data on a magnetic disk is read and written using a magnetization process.
Detailed explanation-2: -A hard disk drive (HDD) is a traditional storage device that uses mechanical platters and a moving read/write head to access data.
Detailed explanation-3: -What is HDD Storage? Hard Disk Drives or HDD, was first introduced by IBM in 1956 and uses magnetism to store data on a rotating platter. A read/write head floats above the spinning platter reading and writing the data.
Detailed explanation-4: -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.
