a ribbon of material, usually with a plastic base, coated on one side (single tape) or both sides (double tape) with a substance containing iron oxide, to make it sensitive to impulses from an electromagnet: used to record sound, images, data, etc.
a long narrow plastic or metal strip coated or impregnated with a ferromagnetic material such as iron oxide, used to record sound or video signals or to store information in computers Sometimes (informal) shortened to mag tape
A plastic tape coated with iron oxide for use in magnetic recording.
A device for storing information, in which signals are recorded by lining up small bits of magnetic materials in the coating on the tape. Ordinary tape recorders use magnetic tape.
