Endless Tape Cartridge
An endless tape cartridge is a tape cartridge or cassette that contains magnetic audio tape that can be played in an endless loop, without the need to rewind to repeat. Description The endless tape cartridge has a tape transport that allows forward movement only. The magnetic tape can have start and end markers, like a magnetic beacon, an electric conductive splice, a hole that can be optically scanned, or a transparent splice tape. The cartridge was invented by sound engineer Bernard A. Cousino and it dominated the North American market for many years. One of the first products that used the endless tape technology was the Audio Vendor from 1952, an invention of Cousino's. It was registered as patent US2804401A. The tape is passed through an inner ring of loose tape reel, where the recording is stored, and looped back through the outer ring of the reel. Initially, this mechanism was to be implemented in a reel-to-reel audio tape recorder. Later, Cousino developed a pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tape Cartridge
A tape cartridge, also known as a tape cart, is a storage medium used for audio recording, video recording, or data storage that includes a magnetic tape housed in a plastic unit that contains a single reel for the tape. The format has become obsolete as an audio and video format but still remains in use for data storage for enterprise and commercial use with new formats and enhanced updates still being released. History The beginning of tape cartridges goes back to loop recording, also known as endless tape recording, which in this case referred to the endless playback of tape read in the tape transport. This was first used in specialized open reel machines that would continuously record or play an endless loop. Endless tape recording was ideal for security footage when the tape was necessary to be stored while endless playback was mainly used for audio. Setting up a reel to reel machine for playback was a common nuisance as it took a lot of time to set up and make sure the tap ...

Traction (engineering)
Traction, traction force or tractive force is a force used to generate Motion (physics), motion between a body and a tangential surface, through the use of either dry friction or shear force. It has important applications in vehicles, as in ''tractive effort''. ''Traction'' can also refer to the ''maximum'' tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the ''coefficient of traction'' (similar to coefficient of friction). It is the force which makes an object move over the surface by overcoming all the resisting forces like friction, normal loads (load acting on the tiers in negative ''Z'' axis), air resistance, rolling resistance, etc. Definitions Traction can be defined as: In vehicle dynamics, tractive force is closely related to the terms tractive effort and drawbar pull, though all three terms have different definit ...

ZX Microdrive
ZX Microdrive unit The ZX Microdrive is a magnetic-tape data storage system launched in July 1983 by Sinclair Research for its ZX Spectrum home computer. It was proposed as a faster-loading alternative to the cassette and cheaper than a floppy disk, but it suffered from poor reliability and lower speed. Microdrives used tiny cartridges containing a endless loop of magnetic tape, which held a minimum of 85 KB and performed a complete circuit in approximately eight seconds. The Microdrive technology was later also used in the Sinclair QL and ICL One Per Desk personal computers. Development It is claimed the Microdrive concept was originally suggested by Andrew Grillet at an interview with Sinclair Research in 1974. Grillet was offered a better-paying job at Xerox, and never worked for Sinclair Research. Development of the ZX Microdrive hardware by Sinclair engineers Jim Westwood, David Southward and Ben Cheese started in 1982. Products Opened microdrive ca ...

HiPac
HiPac (stylized as HIPAC) (pronounced as high-pack), is an audio tape cartridge format, introduced in August 1971 on the Japanese consumer market by Pioneer and discontinued in 1973 due to lack of demand. In 1972 it only achieved a market share of 3% in equipping new cars. In the mid 1970s, the format was repurposed as a children's educational toy called and was used in the analog tape delay "Melos Echo Chamber". Cartridge HiPac is a successor of the PlayTape cartridge, which had been licensed by Tokyo Shibaura Electric around 1970, and had similar dimensions of , which is closer to Compact Cassette than other cartridges containing an endless loop tape. Depending on tape length, the weight of each cartridge is about and used the wider four-track magnetic tape of the compact cassette with The four audio tracks are separated into two stereo programs. The second program is recorded in the same direction as the first, unlike the Compact Cassette.Major Specifications of the " ...

Muntz Stereo-Pak
The Muntz Stereo-Pak, commonly known as the 4- track cartridge, is a magnetic tape sound recording cartridge technology. The Stereo-Pak cartridge was inspired by the Fidelipac 2-track monaural (audio & cue tracks, later 3-track for stereo) tape cartridge system invented by George Eash in 1954 and used by radio broadcasters for commercials and jingles in 1959. The Stereo-Pak was adapted from the Fidelipac cartridge design by Earl "Madman" Muntz in 1962, in partnership with Eash, as a way to play pre-recorded tapes in cars.Jay EhlerEarl Muntz Meets George EashBillboard vol. 84, No. 47, 18 November 1972, p. 62, 76, 78 The tape is arranged in an infinite loop that traverses a central hub and crosses a tape head, usually under a pressure pad to assure proper tape contact. The tape is pulled by tension, and spooling is aided by a lubricant, usually graphite. History The endless loop tape cartridge was designed in 1952 by Bernard Cousino of Toledo, Ohio.

Madman Muntz
Earl William "Madman" Muntz (January 3, 1914 – June 21, 1987) was an American businessman and engineer who sold and promoted cars and consumer electronics in the United States from the 1930s until his death in 1987. He was a pioneer in television commercials with his oddball "Madman" persona; an alter ego who generated publicity with his unusual costumes, stunts, and outrageous claims. Muntz also pioneered car stereos by creating the Muntz Stereo-Pak, better known as the 4-track cartridge, a predecessor to the 8-track cartridge developed by Lear Industries. He invented the practice that came to be known as Muntzing, which involved simplifying otherwise complicated electronic devices. Muntz produced and marketed the first black-and-white television receivers to sell for less than $100, and created one of the earliest functional widescreen projection TVs. He was credited with coining the abbreviation "TV" for ''television'', although the term had earlier been in use in call le ...

Audio Storage
Sound recording and reproduction is the electrical, Mechanical system, 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. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustics, 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 varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Storage
Data storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called ''digital data''. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. Barcodes and magnetic ink character recognition (MICR) are two ways of recording machine-readable data on paper. Recording media A recording medium is a physical material that holds information. Newly created information is distributed and can be stored in four storage media–print, film, magnetic, and optical–and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
