Description
1912 Dictaphone
The at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C. in 1881. When the Laboratory's sound recording inventions were sufficiently developed, Bell and his associates created the Volta Graphophone Company, which later merged with the American Graphophone Company, which itself later evolved into Columbia Records.
The name "Dictaphone" was trademarked by the Columbia Graphophone Company in 1907, which soon became the leading manufacturer of such devices. This perpetuated the use of wax cylinders for voice recording, which had otherwise been eclipsed by disc-based technology. Dictaphone was spun off into a separate company in 1923 under the leadership of C. King Woodbridge.
In 1947, having relied on wax-cylinder recording to the end of World War II, Dictaphone introduced their Dictabelt technology. This cut a mechanical groove into a Lexan plastic belt instead of a wax cylinder. The advantage of the Lexan belt was that recordings were permanent and admissible in court. Eventually IBM introduced a dictating machine using an erasable belt made of magnetic tape which enabled the user to correct dictation errors rather than marking errors on a paper tab. Dictaphone in turn added magnetic recording models while still selling the models recording on the Lexan belts. Machines based on magnetic tape recording were introduced in the late seventies, initially using the standard compact (or "C") cassette, but soon, in dictation machines, using mini-cassettes or microcassettes instead. The size of the cassette was important as it enabled the manufacturer to reduce the size of portable recorders.
