TV Technical Tips No. 20 by Cecil S. Bidlack, NAEB TV Engineer Biggest television news of the past month was made by the Ampex Corporation which demonstrated its new Video Tape Recorder in Chicago at the NARTB Convention. Ampex unveiled this latest development in video recorders April 14 when it demonstrated its new and revolutionary process to over 200 CBS-TV affiliates. CBS-TV has ordered three prototype units at a cost of $75,000 each which it plans to use this fall to overcome the three hour time differential between the East and West Coasts. This new video recorder was demonstrated all week during the NARTB Convention. The tape itself is two inches wide and moves at a speed of only 15 inches per second. An hour f s television program, both sound and picture, can be recorded on a 14 inch reel of tape with no processing involved. The tape can be re¬ wound and played back immediately. It records frequencies as high as 4 me. to give 320 line resolution. A more complete des¬ cription of this equipment is contained in a separate report enclosed with this Newsletter . ***** Many new equipment developments were displayed in the Exposition Hall of the Conrad Hilton Hotel in Chicago April 15-20,
