Magnetic Recording

"The first magnetic recording device was demonstrated and patentedby the Danish inventor Valdemar Poulsen in 1898. Poulsen made amagnetic recording of his voice on a length of piano wire. MAGNETICRECORDING traces the development of the watershed products and thetechnical breakthroughs in magnetic recording that took placeduring the century from Paulsen's experiment to today's ubiquitousaudio, video, and data recording technologies including taperecorders, video cassette recorders, and computer harddrives. An international author team brings a unique perspective, drawnfrom professional experience, to the history of magnetic recordingapplications. Their key insights shed light on how magneticrecording triumphed over all competing technologies andrevolutionized the music, radio, television and computerindustries. They also show how these developments offeropportunities for applications in the future. MAGNETIC RECORDING features 116 illustrations, including 92photographs of historic magnetic recording machines and theirinventors." Sponsored by: IEEE Magnetics Society
