• adjective (Electronics) a ribbon of plastic material to which is affixed a thin layer of powder of a material which can be magnetized, such as ferrite. Such tapes are used in various electronic devices to record fluctuating voltages, which can be used to represent sounds, images, or binary data. Devices such as audio casette recorders, videocasette recorders, and computer data storage devices use magnetic tape as an inexpensive medium to store data. Different magnetically susceptible materials are used in such tapes.
• adjective a telegraph acting by means of a magnet. See Telegraph.
