Magnetic Tape
Magnetic tape is a secondary storage device that store a large volume of data,information or programs permanently on the magnet coated surface.it is available in the form of a large reel, a small cartridge and cassette.however packaged, is made up of plastic strip of which one surface is coated with magnetic materials(iron oxide).it is half inches wide and 50 to 2400 ft long.the tape is divided into vertical columns called frames and horizontal rows called tracks or channels.data are stored on the tape in the form of tiny invisible magnetized and non magnetized spots(representing 1's and 0's)on the magnetic coated surface in sequential tracks along the length of the tape.hence data,information or programs stores on a magnetic tape can be accessed in a sequential storage device.A magnetic tape drive is require to read or write data in a magnetic tape.A magnetic tape is inexpensive so it is specially used in minicomputer and mainframe computer where a large volume of data is needed to store.
