WebMay 11, 2024 · The first working model of a magnetic recording device was demonstrated in 1898 by Danish engineer Valdemar Poulson. He used the mouthpiece from a telephone to convert speech into an electric current. The current went to an electromagnet that recorded the signal on a thin steel wire. WebThe German engineers refined the magnetic tape in the 1930s and 1940s, developing a recorder called the Magnetophon. This type of machine was introduced to the United States after World War II and contributed to the eventual widespread use of the tape recorder.

WebThe principle of magnetic recording is to induce a permanent magnetization in a material by means of the signal to be recorded. The induced magnetization must be proportional to the amplitude of the signal and must remain in the material when the signal is removed.

WebMagnetic Materials: Magnetic Recording Magnetic recording of the human voice was first carried out in 1898 by a Danish engineer, named Poulsen. The recording was made on a ferromagnetic wire, but due to a lack of amplification the recording quality was very poor. In 1927, magnetic tape was simultaneously invented in the USA and Germany. Information is written to and read from the storage medium as it moves past devices called read-and-write heads that operate very close (often tens of nanometers) over the magnetic surface. The read-and-write head is used to detect and modify the magnetisation of the material immediately under it. There are two magnetic polarities, each of which is used to represent either 0 or 1.

WebThis principle was used in the magnetic wire recorder (Telegraphone) invented by Valdemar Poulsen in 1898. While the cylinder wound with steel wire is rotating, the head (soft iron core wound with a coil) is run along the steel wire to record audio signal currents from the microphone onto the steel wire as a magnetization pattern.
