Perforated paper used as input or output media is known as Paper tape.
Punched tape or perforated paper tape is a form of data storage, consisting of a long strip of paper in which holes are punched to store data. Paper tapes constructed from punched cards were widely used throughout the 19th century for controlling looms. Perforated paper tapes were first used by Basile Bouchon in 1725 to control looms. However, the paper tapes were expensive to create, fragile, and difficult to repair.
Data were represented by the presence or absence of a hole at a particular location. Tapes originally had five rows of holes for data. Later tapes had six, seven and eight rows. An early electro-mechanical calculating machine, the Automatic Sequence Controlled Calculator or Harvard Mark I, used paper tape with twenty-four rows.[2] A row of smaller sprocket holes that were always punched served to feed the tape, originally using a wheel with radial teeth called a sprocket wheel. Later optical readers used the sprocket holes to generate timing pulses.
