Magnetic Storage Media of Computer

Magnetic storage media are primary computer storage devices where data is stored on a magnetized material. Floopy disk and hard disk are two common storage media that use the technology of magnetic storage.

Hard Disk: 

A hard disk (also called hard drive, or hard disk drive) is a non-volatile data storage device consisting of one or more metal platters coated with a metal oxide material that allows data to be magnetically recorded on the surface of platters. The disks rotate at a very high speed. Atypical speed is revvolution per minute (rpm) and ,the newest top models spin at rpm. A hard disk can store more data than floopy disk. It is installed inside the CPU (Central Processing Unit) cabinet.
