Magnetic recording tape. Perfected by the Nazis, it is one of the most important innovations in the history of audio, along with Edwin Armstrong’s invention of frequency modulation. These two technologies changed everything.
Magnetic recording in studios, and vinyl microgroove records for homes, first appeared at about the same time — 1947-1948. The transistor was also created in 1947, but it wouldn’t be established in high fidelity audio for another 20 years.
The first tape recorders were brought to America from Germany after World War II by a man named Jack Mullin, who modified one of the units and demonstrated it for Bing Crosby’s technical producer. The tale is told at the end of this link, with the fascinating story of the development of videotape.
On October 1, 1947, two takes of Philco Radio Time with Bing Crosby were recorded magnetically by Mullin, and edited into a single, seamless show. The audio player has a minute of that historic program, preceded by a minute of how Bing sounded on January 29 of that year, using disc recording technology. You may recognize the name of Bing’s guitar player, whose son had a successful career as a record producer and musician, and be sure to catch the name of Bing’s arranger-conductor, who would later have a connection to the Peanuts TV specials.
With Crosby’s financial backing, Ampex began manufacturing tape recorders. One of the first production units was given to Les Paul, who had played guitar for Bing. It’s impossible to overstate the influence of what Les Paul did with his tape recorders.
Here are a couple of captivating videos of Les with Mary Ford, performing two of their best known numbers, taken from films of TV shows. Ironically, Ampex wouldn’t perfect magnetic videotape recording until Les and Mary were off of TV. In the second clip, Les kids around before getting to the real demonstration of how he and Mary did what they did so beautifully. These are worth watching twice — first, for Les, and then for Mary. I eat up this stuff like ice cream.
These clips are being streamed from Oobleckboy on YouTube. The comments are his.
I love Les Paul and Mary Ford! Tom, of course, being born in 1950, is old enough to remember hearing them on the radio. The multi-tracking intrigued the crap out of him, as it did all future engineers. He was already taking stuff apart and putting it back together by the time Dograt and I appeared on the scene in 1955.
