Who invented the wire recorder?
Valdemar Poulsen
Wire recording/Inventors
Vlademar Poulsen invented the Telegraphone, the first wire recorder, with “strung-out piano wire and a primitive electromagnet connected to a microphone” (Jorgenson:1988:7). By passing the electromagnet over the wire as he spoke into the microphone, Poulsen created the first wire recording.
Who invented the magnetic tape recorder?
Ten years later, Valdemar Poulsen, a Danish telephone engineer, invented the world’s first magnetic recorder, called the “Telegraphone,” in 1898.
When was the wire recorders invented?
1898
Wire recording was the first magnetic media recording technology. It was developed by Vlademar Poulsen in 1898 and was in popular use until the late 1940s, when magnetic tape emerged as the choice home and dictation recording medium.
Who invented Magnetophon?
Fritz Pfleumer
Magnetophone, or simply Magnetophon, was the brand or model name of the pioneering reel-to-reel tape recorder developed by engineers of the German electronics company AEG in the 1930s, based on the magnetic tape invention by Fritz Pfleumer.
How did a wire recorder work?
The wire is pulled rapidly across a recording head which magnetizes each point along the wire in accordance with the intensity and polarity of the electrical audio signal being supplied to the recording head at that instant.
What has replaced the tape recorder?
The alternative recording technologies of the era, transcription discs and wire recorders, could not provide anywhere near this level of quality and functionality. As of the first decade of the 21st century, analog magnetic tape has been largely replaced by digital recording technologies.
What are the advantages and disadvantages of magnetic tape?
Magnetic tapes can store up to one terabyte of uncompressed data – as much as can be stored on a hard disk….6. Magnetic Tape.
| Advantages of magnetic tape | Disadvantages of magnetic tape |
|---|---|
| Probably the cheapest form of storage per megabyte of storage | Serial access so can be quite slow to access data |

In what year could you first buy the Magnetophon the world’s first tape recorder?
On 16.08. 1935, the AEG company launched the world’s first tape recorder, the “Magnetophon K1.” The invention of the tape recorder revolutionized music and brought it closer to the public: for the first time, people could make their own recordings of both music and language.
When was the Magnetophon created?
1934
In 1934, Allgemeine Elektricitäts-Gesellschaft (AEG), the German division of General Electric, began manufacturing a tape recorder called the Magnetophon, which used plastic tape coated with magnetic particles and was manufactured by BASF.
What is a police wire?
A “wire” is a device that is hidden or concealed under a person’s clothes for the purpose of covertly listening to conversations in proximity to the person wearing the “wire”. Wires are typically used in police sting operations in order to gather information about suspects.
Do recording studios still use tape?
“Recording studios still use tape! They do, and for a lot of reasons,” said McTear, while standing over his Ampex tape machine. “It’s not that unusual.” A company in York, Pennsylvania, even started manufacturing tape again, giving McTear and others a reliable source.
When did magnetic tape recording replace wire recording?
Magnetic wire recording was replaced by magnetic tape recording, but devices employing one or the other of these media had been more or less simultaneously under development for many years before either came into widespread use. The principles and electronics involved are nearly identical.
What kind of recording is a wire recording?
Wire recording or magnetic wire recording is an analog type of audio storage in which a magnetic recording is made on thin steel or stainless steel wire.
Who was the inventor of magnetic sound recording?
Magnetic recording was conceived of as early as 1877 by the American engineer Oberlin Smith (left) and demonstrated in practice in 1898 by Danish engineer Valdemar Poulsen (right).
When was the peak of wire recording technology?
Dictaphone and Ediphone recorders, which still employed wax cylinders as the recording medium, were the devices normally used for these applications during this period. The peak of wire recording lasted from approximately 1946 to 1954.
