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. [1]

One of the first products that used the endless tape technology was the Audio Vendor from 1952, an invention of Cousino's. [2] 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. [3] [4]

Later, Cousino developed a plastic case that could be hung up on some existing tape recorders. [5] This cartridge was marketed by John Herbert Orr as Orrtronic Tapette. [6]  In this generation, the magnetic coating of the tape was wound on the inside of the reel. Later cartridge types had the magnetic layer aligned to the outside of the cartridge, which required a specially designed recorder to play it. One traction of the tape by capstan was added, which allowed users the convenience of just pushing the cartridge into the recorder without having to thread the tape. These cassettes needed no internal space for the tape head slider because they accessed the tape from outside the cartridge. [7]  

Based on these new cassettes, George Eash developed the Fidelipac cartridge in 1954. [8] PlayTape and the 8-track tape and endless compact cassettes for the announcement text of answering machines were made with this technique. The take-up roll got a table and the perforation for traction was removed.[ clarification needed ] There was no rear winding roll inside such a cassette so rewinding was impossible. Previously, a similar technique was used to store Tefifon's vinyl sonic tape in the Tefi cartridge.

Another invention patented by Cousino was the graphite coating applied to the bottom side of the tape in endless cartridges. [8] [9] [10] The coating allowed endless tape to be pulled out without crinkling it. 8-track cassettes also used the coating which caused the bottom side of the tape to be grey in colour. [11]

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.

<span class="mw-page-title-main">Cassette tape</span> Magnetic audio tape recording format

The Compact Cassette, also commonly called a 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 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 used to refer to the Compact Cassette because of its ubiquity.

The 8-track tape is a magnetic-tape sound recording technology that was popular from the mid-1960s to the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music.

A cassette deck is a type of tape machine for playing and recording audio cassettes that does not have a built-in power amplifier or speakers, and serves primarily as a transport. It can be a part of an automotive entertainment system, a part of a portable mini system or a part of a home component system. In the latter case it is also called a component cassette deck or just a component deck.

It was designed for the PAL color television standard, but some models additionally handled SECAM. Distribution of Video 2000 products began in 1979 exclusively in Europe, South Africa and Argentina and ended in 1988.

<span class="mw-page-title-main">Reel-to-reel audio tape recording</span> Audio recording using magnetic tape spooled on open reels

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 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 1412, 1, or 2 inches wide, which normally moves at 3+347+12, 15 or 30 inches per second. Domestic consumer machines almost always used 14 inch (6.35 mm) or narrower tape and many offered slower speeds such as 1+78 inches per second (4.762 cm/s). All standard tape speeds are derived as a binary submultiple of 30 inches per second.

<span class="mw-page-title-main">Video tape recorder</span> Tape recorder designed to record and play back video and audio material on magnetic tape

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.

Print-through is a generally undesirable effect that arises in the use of magnetic tape for storing analog information, in particular music, caused by contact transfer of signal patterns from one layer of tape to another as it sits wound concentrically on a reel.

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 by inventor George Eash, and commercially introduced in 1959 by Collins Radio Co. at the 1959 NAB Convention. The cartridge was often used at radio stations until the late 1990s, when such formats as MiniDisc and computerized broadcast automation predominated.

<span class="mw-page-title-main">History of multitrack recording</span>

Multitrack recording of sound is the process in which sound and other electro-acoustic signals are captured on a recording medium such as magnetic tape, which is divided into two or more audio tracks that run parallel with each other. Because they are carried on the same medium, the tracks stay in perfect synchronization, while allowing multiple sound sources to be recorded at different times.

<span class="mw-page-title-main">RCA tape cartridge</span> Magnetic tape audio format introduced in 1958

The RCA tape cartridge is a magnetic tape audio format that was designed to offer stereo quarter-inch reel-to-reel tape recording quality in a convenient format for the consumer market. It was introduced in 1958, following four years of development. This timing coincided with the launch of the stereophonic phonograph record. It was introduced to the market by RCA in 1958.

A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette, and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as timeshifting. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings.

<span class="mw-page-title-main">Tefifon</span>

The Tefifon is an audio playback format, developed and manufactured in Germany, that utilizes cartridges loaded with an endlessly looped reel of plastic tape. It is somewhat similar to the later 4-track and 8-track magnetic audio tape cartridges, but with grooves embossed on the tape, like a phonograph record. The grooves were embossed in a helical fashion across the width of the tape, in a manner similar to Dictaphone's Dictabelt format. The grooves are read with a stylus and amplified pickup in the player's transport. A Tefifon cartridge, known as a "Tefi", can hold up to four hours of music; therefore, most releases for the format are usually compilations of popular hits or dance music, operas, and operettas. Tefifon players were not sold by television and radio dealers in Germany, but rather sold directly by special sales outlets affiliated with Tefi.

Bernard August Cousino was an American music technology inventor. He is known for inventing an endless loop tape cartridge design in 1952, known as the Audio Vendor, patented under US2804401A. The tape is pulled from the inside of a loose tape roll making it spin to wind the returning tape onto the roll again. Initially, this mechanism was mounted on a reel to reel tape recorder. Later Cousino developed a plastic housing to be hung up on some tape recorders. First, the magnetic coating was wound to the inside of the reel. This cartridge was marketed by John Herbert Orr as the Orrtronic Tapette. Newer cartridges had magnetic coating wind of the tape outside the reel, which required a special recorder to operate it, but offers comfortable simple inserting the cartridge without threading the tape. This more compact cartridges do not require any bottom spare for the tape head assembly. That would inspire George Eash to make the Fidelipac tape cartridge, which itself would inspire the Stereo-Pak tape cartridge.

George H. Eash was an American inventor of several magnetic tape audio cartridges having a single tape reel. In 1950s he worked next desk to Bernard Cousino, who invented the endless tape loop, using it at first on an open reel. Eash created further cartridges using this tape loop like the Fidelipac, also known as "NAB-Cartridge" or even "cart" and used in broadcast, and as a consultant of Earl "Madman" Muntz the 4-Track cartridge, known as the Muntz Stereo-Pak or CARtridge. With the Lear 8-Track cartridge Eash's patent plea failed.

HiPac, 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 ポンキー and was used in the analog tape delay "Melos Echo Chamber".
