An obsolete but once widely used data medium in the form of a continuous tape of paper with uniform width and thickness and specified physical attributes; other materials included laminates of paper and polyester. Data was encoded by punching patterns of holes on the tape.

Punched paper tape was in use for data communication purposes (telex) prior to its use for computer input/output. It has also been used for programmed control of industrial equipment, and the preprogrammed control of continuous paper through computer printers.
