NTSC, PAL. Developed by. Ampex. Usage. Video production. Ampex VR-2000. 2-inch quadruplex videotape (also called 2″ quad video tape or quadraplex) was the first practical and commercially successful analog recording video tape format. [1] It was developed and released for the broadcast television industry in 1956 by Ampex, an American company ...
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for ...
Type C videotape. 1-inch Type C Helical Scan or SMPTE C is a professional reel-to-reel analog recording helical scan videotape format co-developed and introduced by Ampex and Sony in 1976. It became the replacement in the professional video and broadcast television industries for the then-incumbent 2-inch quadruplex videotape (2-inch Quad for ...
A 14-inch reel of 2-inch quad videotape compared with a modern-day MiniDV videocassette. Both media store one hour of color video. The first commercial professional broadcast quality videotape machines capable of replacing kinescopes were the two-inch quadruplex videotape (Quad) machines introduced by Ampex on April 14, 1956, at the National Association of Broadcasters convention in Chicago.
D-2 (video) D-2 is a professional digital videocassette format created by Ampex and introduced in 1988 [1] at the NAB Show as a composite video alternative to the component video D-1 format. It garnered Ampex a technical Emmy in 1989. [1] Like D-1, D-2 stores uncompressed digital video on a tape cassette; however, it stores a composite video ...
Usage. Video production. 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.
On March 14, 1961, Ampex introduced the first helical scan video recorder, the VR-8000, which recorded video using helical scan recording technology on 2-inch tape. The VR-8000 was made using a similar chassis used by Ampex's 2-inch quadruplex VTRs. Unlike the VR-660, it used only one video head on the scanner with a full alpha wrap.
This used 5-centimetre (2.0 in) wide tapes running at a speed of 38 cm (15 in) per second. The rapid tape-to-head speed of quadruplex videotape was achieved by spinning the heads rapidly on a drum: the system used, with variations, on all videotape systems ever since, as well as DAT. The BBC scrapped VERA and quickly adopted the Ampex system.
