DictionarySeemagnetic tapemagnetic tape head
magnetic tape headThe mechanism that reads and writes magnetic tape as it moves past. Quality tape recorders have three heads: play (read), record (write) and erase. Many consumer products have only two: one that plays and records and another that erases. Machines that record audio for movie film may have a fourth head that writes an inaudible synchronization signal. See magnetic tape.
