Audio Tape Specifications
Since the widespread adoption of reel-to-reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common ones. All tape thicknesses here refer to the total tape thickness unless otherwise specified, including the base, the oxide coating and any back coating. In the United States, tape thickness is often expressed as the thickness of the base alone. However, this varies from manufacturer to manufacturer and also between tape formulations from the same manufacturer. Outside of the US, the overall thickness is more often quoted, and is the more relevant measurement when relating the thickness to the length that can be fit onto a reel or into a cassette. Reel-to-reel quarter-inch The tape decks of the 1950s were mainly designed to use tape wide and to accept one of two reel formats: * reels, almost always with metal flanges, which fit ove ...

Reel-to-reel Audio Tape Recording
Reel-to-reel audio tape recording, also called open-reel recording, is Magnetic tape#Audio, 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 . Domestic consumer machines almost always used or narrower tape and many offered slower speeds such as . 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 .

Inches Per Second
The inch per second is a unit of speed or velocity. It expresses the distance in inches (''in'') traveled or displaced, divided by time in seconds (''s'', or ''sec''). The equivalent SI unit is the metre per second. Abbreviations include in/s, in/sec, ips, and less frequently in s−1. Conversions 1 inch per second is equivalent to: : = 0.0254 metres per second (exactly) : = or 0.08 feet per second (exactly) : = or 0.056 miles per hour (exactly) : = 0.09144 km·h−1 (exactly) 1 metre per second ≈ 39.370079 inches per second (approximately) 1 foot per second = 12 inches per second (exactly) 1 mile per hour = 17.6 inches per second (exactly) 1 kilometre per hour ≈ 10.936133 inches per second (approximately) Uses In magnetic tape sound recording, magnetic tape speed is often quoted in inches per second (abbreviated "ips ...

NAB Cart
The Fidelipac, commonly known as a "NAB cartridge" or simply "cart", is a magnetic tape sound recording format, used for radio broadcasting for playback of material over the air such as radio commercials, jingles, station identifications, and music, and for indoor background music. Fidelipac is the official name of this industry standard audio tape cartridge. It was developed in 1954"Eash hand-made his own plastic cartridge for his first working unit and in 1954 began showing his unit to record people" ... "What Eash did in the Fidelipac cartridge - a term invented in 1956 by a Toledo advertising agency - was splice tape together.""Car Cartridges Come Home" pp.18-22, '' |
Multitrack Recording
Multitrack recording (MTR), also known as multitracking, is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole. Multitracking became possible in the mid-1950s when the idea of simultaneously recording different audio channels to separate discrete ''tracks'' on the same reel-to-reel tape was developed. A ''track'' was simply a different channel recorded to its own discrete area on the tape whereby their relative sequence of recorded events would be preserved, and playback would be simultaneous or Synchronization, synchronized. A multitrack recorder allows one or more sound sources to different tracks to be simultaneously recorded, which may subsequently be processed and mixed separately. Take, for example, a band with vocals, guitars, a keyboard, bass, and drums that are to be recorded. The singer's microphone, the output of the guitars and keys, ...

Mercury Records
Mercury Records is an American record label owned by Universal Music Group. It had significant success as an independent operation in the 1940s and 1950s. Smash Records and Fontana Records were sub labels of Mercury. Mercury Records released rock, funk, R&B, doo wop, soul music, blues, pop, rock and roll, and jazz records. In the United States, it is operated through Republic Records; in the United Kingdom and Japan (as Mercury Tokyo in the latter country), it is distributed by EMI Records. Background Mercury Records was started in Chicago in 1945 and over several decades, saw great success. The success of Mercury has been attributed to the use of alternative marketing techniques to promote records. The conventional method of record promotion used by major labels such as RCA Victor, Decca Records, and Capitol Records was dependent on radio airplay, but Mercury Records co-founder Irving Green decided to promote new records using jukeboxes instead. By lowering promotion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Everest Records
Everest Records was a record label based in Bayside, Long Island, started by Harry D. Belock and Bert Whyte in May 1958. It was devoted mainly to classical music. History The idea for starting a label was related by electronics inventor Harry Belock (who also worked on sound films in Hollywood in the 1930s) to Roland Gelatt in the February 1959 issue of ''High Fidelity'': "The more of them I heard, the more I felt that nobody had a good stereo library. So I decided to get into the business myself." The plan was to record repertory that was new to stereo. Belock was very ambitious, and told ''High Fidelity'' that "We're out to surpass Capitol. We're not shooting marbles." Belock Instrument Corporation, a manufacturer of precision equipment (particularly missile electronics) was the parent of the Everest label 1958-1960 (operated as the Belock Recording Company). Everest would issue its recordings on monaural LP (LPBR 6000 series), stereo LP (SDBR 3000 series), and tape. Ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
35 Mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard negative pulldown, image exposure length on 35 mm for movies ("single-frame" format) is four film perforations, perforations per Film frame, frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th and early 20th centuries, along with various film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film st ...

70 Mm Film
70 mm film (or 65 mm film) is a wide high-resolution film gauge for motion picture photography, with a negative area nearly 3.5 times as large as the standard 35 mm motion picture film format. As used in cameras, the film is wide. For projection, the original 65 mm film is printed on film. The additional 5 mm contains the four magnetic stripes, holding six tracks of stereophonic sound. Although later 70 mm prints use digital sound encoding (specifically the DTS format), the vast majority of existing and surviving 70 mm prints pre-date this technology. Each frame is five perforations tall (i.e., 23.8125 mm or 15/16 inches tall), with an image aspect ratio of 2.2:1. The use of anamorphic Ultra Panavision 70 lenses squeezes an ultra-wide 2.76:1 aspect ratio horizontally into that 2.2:1 imaging area. To this day, Ultra Panavision 70 produces the widest picture size in the history of filmmaking; surpassed only by Polyvision, which was on ...

Magnetophon
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. AEG created the world's first practical tape recorder, the K1, first demonstrated in Germany in 1935 at the Berlin Radio Show. A brief history of magnetic tape from the BASF Historian and the founding curator of the Ampex museum. Later models introduced the concept of AC tape bias, which improved the sound quality by largely eliminating background hiss. The resulting reproduction was so great an advance on any existing recording method that even those well acquainted with the industry could not tell the recordings from live play. Adolf Hitler Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the dictator of Nazi Germany from 1933 until Death of Adolf Hitler, his suicide in 1945.

AEG (German Company)
; AEG) was a German producer of electrical equipment. It was established in 1883 by Emil Rathenau as the ''Deutsche Edison-Gesellschaft für angewandte Elektricität'' in Berlin. The company's initial focus was driven by electrical lighting, as in 1881, Rathenau had acquired the rights to the electric light bulb at the International Exposition of Electricity in Paris. Using small power stations, his company introduced electrical lighting to cafés, restaurants, and theaters, despite the high costs and limitations. By the end of the 19th century, AEG had constructed 248 power stations, providing a total of 210,000 hp of electricity for lighting, tramways, and household devices. During the World War II, Second World War, AEG worked with the Nazi Party and benefited from forced labour from concentration camps. After the war, its headquarters moved to Frankfurt am Main. In 1967, AEG joined with its subsidiary Telefunken, Telefunken AG, creating ''Allgemeine Elektricitäts-Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
