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: -Data is stored on a hard drive in binary code, using 1s and 0s. The information is spread out on the magnetic layer of the disk(s) and are read or written by the read heads that ‘float’ above the surface thanks to the layer of air produced by the ultra fast rotation of the disk.
Detailed explanation-3: -Magnetic storage media and devices store data in the form of tiny magnetised dots. These dots are created, read and erased using magnetic fields created by very tiny electromagnets.
