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 plastic c ...

Tape Cartridge
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 ...

Perforation
A perforation is a small hole in a thin material or web. There is usually more than one perforation in an organized fashion, where all of the holes collectively are called a ''perforation''. The process of creating perforations is called perforating, which involves puncturing the workpiece with a tool. Perforations are usually used to allow easy separation of two sections of the material, such as allowing paper to be torn easily along the line. Packaging with perforations in paperboard or plastic film is easy for consumers to open. Other purposes include filtrating fluids, sound deadening, allowing light or fluids to pass through, and to create an aesthetic design. Various applications include plastic films to allow the packages to breathe, medical films, micro perforated plate and sound and vapor barriers. Processes Pins and needles Rotary pinned perforation rollers are precision tools that can be used to perforate a wide variety of materials. The pins or needles can be ...

Tape Drive
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and a long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data. As a result, tape drives have very large average access times. However, tape drives can stream data very quickly off a tape when the required position has been reached. For example, Linear Tape-Open (LTO) supports continuous data transfer rates of up to 360 MB/s, a rate comparable to hard disk drives. Design Magnetic tape drives with capacities of less than one megabyte were first used for data storage on mainframe computers in the 1950s. , capaci ...

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 Microdrive cartridge with case It is claimed the Microdrive concept was originally suggested by Andrew Grillet at an interview with Sinclair Research in 1974. Grillet proposed "a version of the Learjet Stereo 8 system, modified to allow two 64k core images per track for roll-out roll-in swapping using the KUTS protocol". Grillet was offered a better-paying job at Xerox, and neve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HiPac
HiPac (stylized as HIPAC) (pronounced as high-pack), is an audio Reel-to-reel audio tape recording, tape cartridge format, introduced in August 1971 on the Japanese consumer market by Pioneer Corporation, 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 Delay (audio effect)#Tape based, analog tape delay "Melos Echo Chamber".

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. 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 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, wh ...

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 seen or ...

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] |
