1-inch Type A Helical Scan or SMPTE A is a reel-to-reel helical scan analog recording videotape format developed by Ampex in 1965, that was one of the first standardized reel-to-reel magnetic tape formats in the 1–inch (25 mm) width; most others of that size at that time were proprietary. It was capable of 350 lines.[2]
