English	definition	As opposed to the helical scan system, which uses one head, the Quadruplex videorecording system uses four videorecording heads. Often referred to as Quad, it was developed by Ampex in the mid-1950's. It provided higher quality resolution and color than did helical scanning.	Published
English	scope note	Quadruplex was the broadcast standard until recently, when less expensive helical scan systems have begun to overtake it.	Published
