Fritz Pfleumer
Fritz Pfleumer (20 March 1881 – 29 August 1945) was a German engineer who invented magnetic tape for recording sound. Biography Fritz was born as the son of Robert and Minna, née Hünich. His father Robert (1848–1934) was born in Greiz, and his mother Minna (1846–1932) was born in Freiberg. Fritz had five siblings – Mimi, Hans, Hermann, Otto, and Mizi. Hans emigrated to the US. Pfleumer developed a process for putting metal stripes on cigarette papers and reasoned that he could similarly coat a magnetic stripe to be used as an alternative to wire recording. In 1927, after experimenting with various materials, Pfleumer used very thin paper that he coated with iron oxide powder using lacquer as glue. He received a patent in 1928. On 1 December 1932 Pfleumer granted AEG the right to use his invention when building the world's first practical tape recorder, called Magnetophon K1. It was first demonstrated at the IFA in 1935.

Radebeul
Radebeul ( hsb, Radobyle) is a town (''große Kreisstadt'') in the Elbe valley in the district of Meißen (district), Meißen in Saxony, Germany, a suburb of Dresden. It is well known for its viticulture, a museum dedicated to writer Karl May, and a narrow gauge railway connecting Radebeul with the castle of Moritzburg, Saxony, Moritzburg and the town of Radeburg. The Meißen area, where Radebeul is located, is one of the northeasternmost areas where wine is grown in the 21st century. It is sometimes called the "Nice of Saxony" for its pleasant landscape and mild climate. History A village Radebeul was first mentioned in 1349. In 1905 it absorbed the neighboring village of Serkowitz. On April 1, 1924 Radebeul became a town. Meanwhile, the neighboring village of Kötzschenbroda had taken over Lindenau in 1920, and Naundorf, Zitzschewig und Niederlößnitz by 1924, when it was made a town as well. In 1934 Wahnsdorf and Oberlößnitz joined Radebeul, and on January 1, 1935 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Tape
Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape could with relative ease record and playback audio, visual, and binary computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing. Since the early 1950s, magnetic tape has been used with computers to store large quantities of data and is still used for backup purposes. Magnetic tape begins to degrade after 10–20 years and therefore is not an ideal medium for long-term archival storage. Durability While good for short-term use, magnetic tape is highly prone to disintegration. Depending on the environment, this process may begin after 10–20 years. Over time, magnetic tape made in the 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Greiz
Greiz () is a town in the state of Thuringia, Germany, and is the capital of the district of Greiz. Greiz is situated in eastern Thuringia, east of state capital Jena, on the river ''White Elster''. Greiz has a large park in its center (Fürstlich Greizer Park) which is classified as an English garden. Thomasstraße, Burgstraße, Marktstraße, Waldstraße, and Leonhardtstraße with their Jugendstil houses are well known examples of that architectural style. Prof.-Dr.-Friedrich-Schneider-Straße 4 is one of the earliest examples of Art Deco architecture (built in 1911). History As with other nearby settlements, the place name (originally ''Grouts'') is of Slavic origin and means '' gord''. The first documented mention of the settlement dates from 1209. The prime location of Greiz on the confluence of the White Elster river and its tributary Göltzsch helped to make it a fast-growing town. It was recognized as a town in the 13th century.

Tape Recorder
An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage. The use of magnetic tape for sound recording originated around 1930 in Germany as paper tape with oxide lacquered to it. Prior to the development of magnetic tape, magnetic wire recorders had successfully demonstrated the concept of magnetic recording, but they never offered audio quality comparable to the other recording and broadcast standards of the time. This German invention was the start of a long string of innovations that have led to present-day magnetic t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
