Can you believe that companies like RCA knew nothing about magnetic tape recording? It would be a big threat to recording media in this country, and it proved to be just that. It was in use in Germany in the mid thirties, but unheard of here untol Jack Mullin brought a couple of Magnetophon machines back from Europe. It's sort of like magnetic tape recording. The holding back of the 45 system was Sarnoff's doing, and he paid a big price for it. I speculate that one of the thorns in Sarnoff's side was the failure of the 1932 RCA system, and the success of Goldmark's Columbia system, both using the 33 1/3 RPM speed. The LP records disappeared from the catalogues about 1934. The grooves were (apparently) 3 mil, as were those on the 78 RPM records. They had half of the idea, in using 33 1/3 RPM turntable speed.
