Poulsen Telegraphone recorder from 1922 A Webster-Chicago Model 7 wire recorder from 1948. Wire recording, also known as magnetic wire recording, was the first magnetic recording technology, an analog type of audio storage. It recorded sound signals on a thin steel wire using varying levels of magnetization.
Marvin Camras (January 1, 1916 – June 23, 1995) was an electrical engineer and inventor who was widely influential in the field of magnetic recording. Camras built his first recording device, a wire recorder, in the 1930s for a cousin who was an aspiring opera singer named Willy. He also built Willy a telephone, because he could not afford ...
Valdemar Poulsen (23 November 1869 – 23 July 1942) was a Danish engineer who developed a magnetic wire recorder called the telegraphone in 1898. He also made significant contributions to early radio technology, including the first continuous wave radio transmitter, the Poulsen arc, [1] which was used for a majority of the earliest audio radio transmissions, before being supplanted by the ...
It started with a wire recorder in 1947. More than 70 years later, John Miley has one of the largest collections of sports recordings in the world.
Ring-and-spring microphones, such as this Western Electric microphone, were common during the electrical age of sound recording c. 1925–45.. The second wave of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in ...
By the 1950s it was the leading manufacturer of wire recorders in the United States. [3] The wire recorder business was short-lived. In 1952 Webcor introduced its first magnetic tape recorder, and by 1955 magnetic tape recorders overtook wire ones. [4] In the 1960s the firm began to face strong competition from German and Japanese imports.
The first wire recorder was the Telegraphone invented by Valdemar Poulsen in the late 1890s. Wire recorders for law and office dictation and telephone recording were made almost continuously by various companies (mainly the American Telegraphone Company) through the 1920s and 1930s.
Ludwig Blattner, also known as Louis Blattner, [2] was a pioneer of early magnetic sound recording, licensing a steel wire-based design from German inventor Dr. Kurt Stille, [citation needed] and enhancing it to use steel tape instead of wire, thereby creating an early form of tape recorder. This device was marketed as the Blattnerphone. [3]
