This website and mailing list is focused on 2" Quadruplex Videotape: Sharing your experiences working with Quad tapes, recorders, their quirks and foibles can be very helpful in migrating the thousands of aging Quad videotapes now just sitting on shelves at archives world-wide. Members of this group are working with the Library of Congress National Audio Visual Conservation Center in Culpeper, Virginia at the request of Steven Nease, the Chief Technology Officer for the NAVCC. Historical stories or personal recollections are welcome. We all need a laugh, an "Ah-Ha!" or to |

The Videotape Editor was Jack Shultis, according to a booklet produced about the show, Quad Videotape Group Quad History Replay: 51 years ago—1960: 41 years ago—1970: First shown as a prototype at the 1969 NAB, the TCR-100 cart recorder/player was used for short-length elements like commercials, promos and news stories. Ampex made three significant product introductions during 1970: The first was in late January, when it announced the ADR-150 high-speed Quad Videotape Duplicating System, recently discussed on the QuadList. The equipment could crank out five copies of a one-hour program in about ten minutes.
The system used a "mirror image" tape made with high coercivity tape on The AVR-1 was formally introduced at NAB 1970. This machine could go from stop to clean picture in five frames, used vacuum columns to smooth tape handling and increase responsiveness, automatically selected the tape format and television standard, and could play a tape that didn't have a control track. Among other things. The AVR-1 It is widely regarded as the pinnacle of Quad recorder evolution. Product three was the ACR-25 Quad cartridge recorder, which used much technology from the AVR-1. It could handle longer program elements than its RCA competitor, and could run separate 10-second carts back to back. MTV used a pair of "modified for stereo" ACR-25's to play its music videos and other short program elements. QuadPEOPLE 1970 Ampex Engineer (and later VP) Charles Anderson received the first Annual Alexander M. Poniatoff Award (cash and a gold medal) for proposing in late 1954 and creating in January, 1955, the original FM video recording system used in development of the Quad video recorder. The FM method is still widely used today for recording analog and digital signals to magnetic media of many kinds. Anderson also designed the console and internal electronics for the Ampex Mark IV Quad machine that first demonstrated Videotape® recording to a stunned group of CBS affiliate brass. Another Ampex engineer named Charles received the 1970 Institute of Electrical and Electronics Engineers (IEEE) Vladimir Zworykin Television Prize, named for the famous RCA engineer. Coleman also recieved another award in 1970 with an RCA "name": The David Sarnoff Medal This honor was "For many original inventions, in particular for time domain electronic signal correction and for the conception and development of high band color videotape recording." While at CBS-owned WBBM-TV, Chicago, Coleman invented the ColTec, which corrected geometric distortions in Coleman later helped develop High-Band FM recording for videotape as implemented in the Ampex VR-2000, and according to "Magnetic Recording: The First 100 Years" invented the Velocity Compensator (Velcomp) that Read about user's experiences with the ACR-25, TCR-100 and the Ampex digital ACR-225 Click here to check out those topics and more in the archives.
