In the computing world, storage of information is very important (Bloomfield 392). The safety of the stored information is of concern. Memory space required for storage of information should be considered when choosing the method of storage. Magnetic storage involves the storage of information on a magnetic medium. The major magnetic storage medium is the hard disk drive. It is used for storage of both video and audio information. Other magnetic storage mediums include magnetic stripes, magnetic tapes, and floppy disks (Bloomfield 392). The operation of the analog magnetic recording utilizes both electricity and magnetism. Initially, the recording magnetic tapes are empty and in demagnetized state. The writing heads are supplied with an energy, which is relative to the information being recorded. Thereafter, the tape is made to rotate at a constant speed. The combination of the two leads to the magnetization of the tape, hence the recording takes place. When information has been stored, it can be accessed via redheads. The operations of magnetic recording require the use of electric current on the read and write heads to create magnetization on the magnetic medium for storage.
