Dictaphone was spun off into a separate company in 1923 under the leadership of C. King Woodbridge. [2] In 1947, having relied on wax-cylinder recording to the end of World War II, Dictaphone introduced its Dictabelt technology. This cut a mechanical groove into a Lexan plastic belt instead of into a wax cylinder. The advantage of the Lexan ...
Transcribing dictation with a Dictaphone wax cylinder dictation machine, in the early 1920s. Note supply of extra wax cylinders on lower part of stand. A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print. It includes digital voice recorders and tape recorder.
Cylinder phonograph technology continued to be used for Dictaphone and Ediphone recordings for office use for decades. [ 23 ] In 1947, Dictaphone replaced wax cylinders with their Dictabelt technology, which cut a mechanical groove into a plastic belt instead of into a wax cylinder.
The Dictabelt system was popular, and by 1952, made up 90% of Dictaphone's sales. [5] Dictabelts were more convenient and provide better audio quality than the reusable wax cylinders they replaced. The belts can be folded for storage and will fit into an ordinary letter-size envelope. However, the plastic loses flexibility as it ages.
Woodcut of the use of an early wax cylinder phonograph, or gramophone, for dictation. Although the phonograph was first invented by Thomas A. Edison, the source text says this was a machine called the 'G', invented by Alexander Graham Bell, Chichester A. Bell, and Sumner Tainter. The user turns the cylinder by pumping the treadle, and speaks ...
This was because many executives (included IBM's own) were reluctant to use dictation machines. IBM was the market leader by 1965, outselling their biggest competitor Dictaphone and driving Ediphone (a division of Edison) out of the market. [2] Unit sales peaked in 1969 at 98,000 units, which was roughly a 33% market share. [3]
Charles Sumner Tainter (April 25, 1854 – April 20, 1940) was an American scientific instrument maker, engineer and inventor, best known for his collaborations with Alexander Graham Bell, Chichester Bell, Alexander's father-in-law Gardiner Hubbard, and for his significant improvements to Thomas Edison's phonograph, resulting in the Graphophone, one version of which was the first Dictaphone.
