Magnetic disk is used as a storage device in computer architecture, whose job is to store data. A magnetic disc is made up of a set of circular plates. These plates are made from non-magnetic materials such as aluminum, aluminum alloys, glass, ceramics and then a magnetic film is placed on these plates which stores the data.



This layer is 10 to 20 nanometers, after which it is applied to a normal metal. These plates are then mounted inside a rotary drive, where the magnetic surface is present and these plates then move closer to the read and write. Each round of which consists of a magnetic coil and a magnetic yoke.
