Open-reel
Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the ''supply reel'' (or ''feed reel'') containing the tape is placed on a spindle or hub. The end of the tape is manually pulled from the reel, threaded through mechanical guides and over a tape head assembly, and attached by friction to the hub of the second, initially empty ''takeup reel''. Reel-to-reel systems use tape that is wide, which normally moves at . All standard tape speeds are derived as a binary submultiple of 30 inches per second. Reel-to-reel preceded the development of the compact cassette with tape wide moving at . By writing the same audio signal across more tape, reel-to-reel systems give much greater fidelity at the cost of much larger tapes. In spite of the relative inconvenience and generally more expensive media, reel-to-reel systems developed in the early 1940s remained popular ...

Video Tape Recorder
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. Beginning in 1963, videotape machines made instant replay during televised sporting events possible. Improved formats, in which the tape was contained inside a videocassette, were introduced around 1969; the machines which play them are called videocassette recorders. An agreement by Japanese manufacturers on a common standard recording format, which allowed cassettes recorded on one manufacturer's machine to play on another's, made a consumer market possible; and the first consumer videocassette recorder, which used the U-matic format, was introduced by Sony in 1971.

Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge and reel ...

Denon
is a Japanese electronics company started in 1910 by Frederick Whitney Horn, an American entrepreneur. Denon produced the first cylinder audio media in Japan and players to play them. Decades later, Denon was involved in the early stages of development of digital audio technology, while specializing in the manufacture of high-fidelity professional and consumer audio equipment. Denon made Japan's first professional disc recorder and used it to record the Hirohito surrender broadcast. For many decades, Denon was a brand name of Nippon-Columbia, including the Nippon Columbia record label. The Denon brand came from a merger of Denki Onkyo (not to be confused with the other Onkyo) and others in 1939. In 2001, Denon was spun off as a separate company with 98% held by Ripplewood Holdings and 2% by Hitachi. In 2002, Denon merged with Marantz to form D&M Holdings. On March 1, 2017, Sound United LLC completed the acquisition of D+M Holdings. History The company was initially named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Recording
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a ...

Blattnerphone
Ludwig Blattner (1881 – 30 October 1935) was a German-born inventor, film producer, director and studio owner in the United Kingdom, and developer of one of the earliest magnetic sound recording devices. Career Ludwig Blattner, also known as Louis Blattner, was a pioneer of early magnetic sound recording, licensing a steel wire-based design from German inventor Dr. Kurt Stille, and enhancing it to use steel tape instead of wire, thereby creating an early form of tape recorder. This device was marketed as the Blattnerphone. Whilst on a promotional tour of his sound recording technology in 1928 he would choose ladies from the audience to dance with to music being played from a Blattnerphone. Prior to the First World War, Blattner was involved in the entertainment industry in the Liverpool City Region: he managed the "La Scala" cinema in Wallasey from 1912 to 1914, conducted the cinema's orchestra, and composed a waltz "The Ladies of Wallasey". In about 1920 he moved to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

List Of Magnetic Tape Cartridges And Cassettes
Magnetic tape cartridge and magnetic tape cassette both refer to a small plastic unit containing a length of magnetic tape on at least one reel. The unit may contain a second "take-up" reel or interoperate with such a reel in an associated tape drive. At least 142 distinct types have been known to exist. The phrase ''cassette tape'' is ambiguous in that there is no common dictionary definition so depending upon usage it has many different meanings, as for example any one the one of 106 different types of audio cassettes, video cassettes or data cassettes listed aThe Museum of Obsolete Media The phrase ''cartridge tape'' is also ambiguous with 36 different types of audio, video or data cartridges listed at The Museum of Obsolete Media. From time to time the terms tape cartridge and tape cassette are used to describe the same product. In current production are the Cassette tape, the LTO tape cartridge and the IBM 3592 tape cartridge. Audio * Analog based ** Cassette tape, a ...

Ton S
Ton is the name of any one of several units of measure. It has a long history and has acquired several meanings and uses. Mainly it describes units of weight. Confusion can arise because ''ton'' can mean * the long ton, which is 2,240 pounds * the short ton, which is 2,000 pounds * the tonne, also called the ''metric ton'', which is 1,000 kilograms or 1 megagram. Its original use as a measurement of volume has continued in the capacity of cargo ships and in terms such as the ''freight ton'' and a number of other units, ranging from in capacity. Recent specialized uses include the ton as a measure of energy and as a means of truck classification. It can also be used as a unit of energy, or in refrigeration as a unit of power, sometimes called a ''ton of refrigeration''. Because the ton (of any system of measuring weight) is usually the heaviest unit named in colloquial speech, its name also has figurative uses, singular and plural, informally meaning a large amount or quan ...
