Question 1: Who invented the tape recorder and in what year? In 1898, Danish scientist Paulson developed the first magnetic tape recorder based on Smith's theory. In 1900, the magnetic tape recorder invented by Paulson was exhibited at the Paris Exposition. Because this type of recorder records sound on steel wire, it has unique advantages compared with phonographs. At the fair, it was favored by people. However, magnetic recording requires high-quality steel wire and steel tape, and is very bulky and inconvenient to use. Therefore, in 1930, Germany's Frauima proposed a new plan, which was to replace steel wire or steel belts with paper tapes or plastic tapes coated with iron powder. After six years of hard work, Frauima developed the tape recorder in 1936. Compared with magnetic tape recorders, this kind of tape recorder has clear and stable sound, is easy to use and is cheap. Marvin built a wire recorder using the new principle in 1937. It uses a complete magnetic coil as the magnetic head, and the steel wire passes through the coil and maintains a certain distance from the magnetic coil, so that the air gap around the steel wire can be used for recording. Because this layer of air gap surrounds the surface of the steel wire, it is uniform. The performance of this recorder is much better than previous recorders. It has realistic sound and beautiful sound quality. After Marvin's cousin sang to his heart's content, the tape recorder played it back. People joked: "The singing level of this 'amateur singer' improved many times in an instant." After that, Marvin said this again. The tape recorder was improved and made into a lightweight and thin plastic tape. After that, he also invented the "high-fidelity multi-channel stereo" playback device.

Since then, Marvin has improved the tape recorder and made a lightweight and thin plastic tape. After that, he also invented the "high-fidelity multi-channel stereo" playback device.
Question 4: The history of the tape recorder The earlier tape recorder was called the phonograph, which was born in 1877 and was made by Edison, the world-famous inventor.
Edison took advantage of the phenomenon that the diaphragm in the telephone microphone would vibrate with the sound of speaking. He experimented with a short needle and got great inspiration from it. The speed of speaking can cause the short needle to vibrate in different ways. Then, in turn, this vibration must also produce the original speaking sound. So he began to study the problem of sound reproduction. On August 15, 1877, Edison asked his assistant Cressey to make a strange machine consisting of a large cylinder, a crank, a receiver and a diaphragm according to the drawings. Edison pointed to this strange machine and said to his assistant: "This is a talking machine." He took out a piece of tin foil, rolled it on a metal cylinder engraved with spiral grooves, and let the end of the needle gently rub the tin foil to rotate. , the other end is connected to the receiver. Edison turned the crank and sang "Mary had a little lamb, and the snowballs were like fur..." into the receiver. After singing, put the needle back to its original place and gently crank the crank again. Then, the machine slowly turned around and over, singing "Mary Had a Little Lamb...", exactly the same as what Edison sang just now. The assistants nearby were so surprised that they were speechless when they encountered a talking machine. The news of the birth of the "talking machine" caused a sensation all over the world. In December 1877, Edison publicly performed the phonograph, and outside public opinion immediately hailed him as the Napoleon of science and one of the three most exciting inventions of the 19th century. The upcoming Paris World's Fair will immediately display it as a fashionable exhibit. Even U.S. President Hayes played at the gramophone for more than two hours. Ten years later, Edison improved the large cylinder and small crank on the phonograph into a device similar to a clock spring. The motor drove a large, thin wax disc to rotate, and the phonograph became widely popular. Although Edison invented the phonograph and realized recording. But the tape recorders at that time mainly used mechanical principles to reproduce sound. The sound volume it records is so low that you have to shout loudly into the speaker when recording. In order to improve this recording method, Danish scientist Paulson used the principle of telephone sound transmission and began to try to store sound magnetically. Paulson used steel wires to conduct experiments. Under the action of magnetic force, the steel wires will become magnets. After the magnetic force disappears, the steel wires in the magnetic field will still retain their magnetism. This retained magnetism is called residual magnetism. Paulson wound a long piece of steel wire onto a reel. The wire was connected to another reel via an electromagnet, and a recording microphone was connected to the coil of the electromagnet. In this way, the energized electromagnet turns the electromagnetic signal in the phone into a magnetic field. The steel wire in the magnetic field is magnetized, producing residual magnetism that varies in intensity with the sound, and the sound is recorded on the steel wire. Because this kind of magnetic recording requires high-quality steel wire and steel tape, and is bulky and inconvenient, it has affected the popularity of this recording method. American radio amateur Marvin Kamras played a key role in the widespread popularity of tape recorders. When he was studying the problem of damage to recording signals, he came up with the idea: The magnetism on the surface of the steel wire is always the same. If the sound can be recorded evenly on the surface of the steel wire, wouldn't it be possible to obtain a uniform sound signal? The principle of the tape recorder at that time was to use a metal pointer as a recording needle to contact the surface of the steel wire. In this way, only the steel wire at the contact point between the two was magnetized, resulting in uneven recording. Kamras wanted to use a magnetic head to improve it, that is, use a complete magnetic circle as the magnetic head, pass the steel wire through the magnetic circle and keep an equal distance between the two, and then use the air gap around the steel wire to record. Compared with the former, Kamras' improvement lies in the use of air gaps instead of metal pointers during the recording process to avoid the destruction of magnetic signals. The real popularity and practical application of the tape recorder came after the invention of the magnetic tape. In 1935, German scientist Lao Yerma invented magnetic tape to replace steel wire. This kind of tape is based on paper tape and plastic bag. The tape base is coated with an iron-based powder called ferric oxide and bonded together with chemical colloid. This tape is not only very lightweight, but also tough and easy to cut. Subsequently, Folayema ??applied iron powder to paper bags to replace steel wires and steel belts, and achieved success in 1936. Paper tape is cheap, easy to carry, and is recognized and accepted by people. Inventor Kamras is not far behind. Near the end of World War II, Kamras discovered a magnetic particle called iron oxide powder. He mixed the powder into lacquer or varnish and applied it to paper strips and paper plates.
When the paint is still wet, put it into a magnetic field. Under the influence of the magnetic field, all the particles will be arranged in a certain direction...>>
Question 5: Cassette tape When was it invented? Although World War II caused the shrinkage of the 78-rpm record market, it inadvertently helped the pop music market in another way. It turns out that in order to better broadcast Hitler's speeches, German engineers made revolutionary progress in tape recording technology after years of research. After World War II, the United States took this technology over and quickly applied it in the field of popular music. Tape recording was convenient, reliable, cheap, and of good quality, allowing small recording companies with little investment to survive, and contributed greatly to the development of independent recording companies in the 1950s. As mentioned earlier, the rise of these small companies directly contributed to the birth of rock and roll. In the mid-1960s, RCA invented the eight-track tape (8-Track) that could be used in cars. This invention immediately attracted the attention of many consumers who had not bought records before. Music sales in the United States also evolved from this period. Start going straight up. In the early 1970s, a group of drug addicts who called themselves Downers (as opposed to the traditional Higher) found that listening to deafening heavy rock music in high-speed cars was very helpful in achieving their state of mind. This statement quickly spread among listeners and was largely responsible for the popularity of heavy rock in the early 1970s. A group of heavy rock bands have benefited greatly from this, such as Deep Purple, Black Sabbath and AC/DC. Their tape sales often account for more than 70% of total sales. Later, the invention of Dolby technology brought recordable cassette tapes into consumers' homes. This new technology allowed pirated tapes to begin to proliferate underground. Record dealers had no choice but to resort to legal means to fight against the broadcast industry just as they did back then. However, the recording quality of tapes is not as good as that of LPs. In addition, due to various reasons, the American pop music market was extremely prosperous in the 1960s and 1970s. Therefore, the impact of piracy is not too bad, but some fans exchange privately recorded music in the underground market. The recording of the singer's live performance can make up for the shortcomings of the studio recording. These illegal recordings not only created a group of die-hard fans for the band, but also greatly helped music historians to study this history.
Question 6: In what era did the earliest recorders appear? Recording can be traced back to 1877 when American inventor Edison invented the phonograph. Edison converted sound waves into vibrations of a metal needle and burned them on tinfoil. He used tinfoil and metal needles to achieve recording. In 1896, Poulsen, a young Danish electrical engineer, converted sound waves into current, then into magnetism, and stored the magnetism on piano wires, realizing magnetic recording, and obtained a patent in 1898. But the real popularity of the tape recorder came after the invention of magnetic tape. In 1935, German scientist Frauyema invented magnetic tape, coating an acetate tape base with iron oxide and officially replacing steel wire. In 1962, the Dutch company Philips invented the cassette tape recorder.
Since the invention of the world's first portable recording device in 1957, the development history of Philips' recording products has exceeded 50 years.
TASCAM belongs to the TEAC Group and is a world-renowned manufacturer of home recording equipment. TASCAM invented the world's first 4-track recorder, the first RDAT recorder, the first digital multitracker and so on.

The recording of the singer's live performance can make up for the shortcomings of the studio recording. These illegal recordings not only created a group of die-hard fans for the band, but also greatly helped music historians to study this history.
Question 8: Who invented the first record player in the world? What time? Which country are you from? In 1857, French inventor Scott invented the sonic vibrator, which was the earliest primitive tape recorder and the originator of the phonograph. In 1877 Edison invented a recording device. Sound waves can be converted into vibrations of a metal needle, and then the waveforms can be burned onto the tin foil of a cylindrical wax tube. When the needle travels along the burned track again, the remaining sound can be reproduced. This device recorded Edison reading the lyrics of "Mary Had a Little Lamb": "Mary held the lamb, its wool as white as snow." A total of 8 seconds of sound became the first sound in the history of world recording. In 1878, Edison founded a phonograph company to produce commercial tinfoil recording tubes. This is the world's first generation sound carrier and the first commercial gramophone. In 1885, American inventors Chichester Bell and Charles Tonter invented the gramophone, a device that used a round cardboard coated with wax to record sounds. In 1887, Emil Berliner, a German living in the United States, obtained a patent for a phonograph and successfully developed disc-shaped records (also called butterfly records) and flat-type phonographs. In 1888, the world's first butterfly record and phonograph produced by Berliner were exhibited in Philadelphia, USA. In 1891, Berliner successfully developed records using shellac as raw material and invented the method of making records. In 1895, Edison founded the National Phonograph Company to produce and sell spring-driven phonographs. In 1898, Berliner founded the British Gramophone Company in London and set up its factory in Hannover, Germany. In 1898, Danish engineer Poulsen invented a practical magnetic tape recorder (wire tape recorder). In 1912, cylinder recording was eliminated. In 1924, Maxfield and Harrison successfully designed an electric record engraving head. Bell Labs successfully conducted electrical recording, and recording technology was greatly improved. 1925 The world's first record player was born. In 1931, the Radio Corporation of America (RCA) successfully trial-produced a 331/3 rpm record (Long Play, referred to as LP). In 1945, the British Decca Company used the pre-emphasis method to expand the high-frequency recording range and recorded a 78 rpm rough record (Standard Play, SP for short). In 1948, the American Columbia Company began mass production of a new generation of 331/3 rpm Microgroove records, which became an epoch-making event in the history of record development. RCA also launched another system of its own - the 45-rpm EP (Extended Play) to compete with it. In 1935, the General Electric Company in Berlin, Germany, successfully developed a tape recorder using plastic tape.
1963 Audio cassette tapes are produced in the Netherlands. The golden age of records is slowly passing.
Question 9: When was recording technology invented? And when was it popularized? When he was working as a waiter, Edison often thought about using a clever device to preserve all kinds of sounds. Come down and whenever you want to listen, just take it out and play it. He was only sixteen or seventeen years old at that time, and it was not until he was 30 years old, in August 1877 to be exact, that he invented the phonograph. (This is the earliest "recording" technology)
When Edison first invented the phonograph, he invited many reporters and civilians to witness it, and people were amazed by the phonograph's performance. Reporters wrote reports, and many people were also interested in this new machine. The phonograph actually became popular very quickly. (Soon this invention spread all over the world, but it was not yet popular)
In the spring of 1878, Edison held a phonograph exhibition in England. The French government also awarded Edison a prize for this invention. He was received at the White House by the President of the United States, who and officials alike praised the gramophone performance. (Already promoted) However, Edison also believed that new things would not be accepted so quickly, but the fact is that after Edison improved the phonograph, phonographs with clearer and more realistic sounds were widely used. (Promotion was successful) Until his later years, Edison continued to improve the phonograph...
