Type A videotape

1 inch type A (designated Type A by SMPTE) is an open-reel helical scan videotape format developed by Ampex in 1965, that was one of the first standardized open-reel videotape formats in the 1 inch (25 mm) width (most others of that size at that time were proprietary).

Type A was developed as mainly an industrial & institutional format (where it saw the most success). It was not widely used for broadcast television, since it did not meet Federal Communications Commission specifications (at the time) for broadcastable videotape formats (the only format passing the FCC's muster at the time was the then-industry-standard 2 inch Quadruplex).

The type A format was later replaced by the 1 inch type C videotape format (which was based on type A), manufactured by Ampex, Sony and Hitachi.
