Answer 2

Hard disk is a common data storage used in computers. Data is stored on the hard disk in the form of 0 and 1. Through this article we will find out how actually data is stored on the hard disk drive. The part of the hard disk that stores the data is known as platter. Platters are circular disk made of a non magnetic material typically aluminum alloy, glass or ceramic and are coated with a thin layer (10-20nm) of a magnetic material. Platters are further separated in to the tracks and sectors where tracks are concentric circles while sectors are pie shaped wedges on the track.
