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 and 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 for broadcast 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 received broad use by the White House Communications Agency from 1966 to 1969. The WHCA, under U.S. President Lyndon B. Johnson, used the format to videotape television broadcasts off the air or from direct White House feeds.^[1] The WHCA recorded programs and events including television appearances by President Johnson, special news broadcasts and news interview programs. Beginning on April 1, 1968, the WHCA taping system was expanded to also include daily morning and evening news programs, both network and local. When U.S. President Richard M. Nixon succeeded Johnson in office in 1969, the WHCA's Type A recording system was continued until it was gradually phased out, later that year, in favor of a recording system using a 2 inch format.^[2]

The Ampex 1 inch 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.
