FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -For these reasons, tape is the most widely used of the various magnetic recording mediums. It consists of a narrow plastic ribbon coated with fine particles of iron oxide or other readily magnetizable material.

Detailed explanation-2: -Hard-disk drives represent the most widely used form of magnetic storage in use today. A hard-disk drive consists of a rigid disc made with non-magnetic material, which is coated with a thin layer of magnetic material. Data is stored by magnetizing this thin film.

Detailed explanation-3: -The magnetic recording process involves relative motion between a magnetic medium and a stationary or rotating read/write magnetic head. Under steady operating conditions, a load-carrying air film is formed. There is a physical contact between the medium and the head during starting and stopping.

Detailed explanation-4: -Magnetic audio tape is used to capture speech and music, and magnetic videotape provides a low-cost medium for recording analog voice and video signals directly and simultaneously. Magnetic technology has other uses in the direct recording of analog information, including alphanumerics.

Detailed explanation-5: -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.
