In early 1951, Bing Crosby asked his Chief Engineer John T. (Jack) Mullin if television could be recorded on tape as was the case for audio. Mullin said that he thought that it could be done. Bing asked Ampex to build one and also set up a laboratory for Mullin in Bing Crosby Enterprises (BCE) to build one. In 1951 it was believed that if the tape was run at a very high speed it could provide the necessary bandwidth to record the video signal. The problem was that a video signal has a much wider bandwidth than an audio signal does (6 MHz vs 20 kHz), requiring extremely high tape speeds to record it. However, there was another problem: the magnetic head design would not permit bandwidths over 1 megahertz to be recorded regardless of the tape speed.
