Full Answer

Magnetic tape is composed of plastic, one side of which has a ferromagnetic coating. Most tapes have tracks that runs parallel to the edge for linear recording. Some, however, have diagonal tracks. Storage capacity has improved greatly over time. One drawback to the magnetic tape medium is that tapes have to be recopied from time to time because of the possibility of the magnetic surfaces coming in contact with one another. Another major drawback is that finding information on magnetic tape is difficult, so it is best used for archiving material that is not often referenced.
