Definição do conceito
[SPA] Fidelipac | El Fidelipac, comúnmente conocido como «cartucho NAB» o simplemente «cart», es un formato de cinta magnética de grabación de audio, utilizado en las emisoras de radio para la reproducción de material por aire, como comerciales, jingles, identificación de la estación y música. Fidelipac es el nombre oficial de este cartucho de cinta de audio estándar industrial. Fue desarrollado en 19541? por el inventor George Eash2?3? (aunque la invención del cartucho Fidelipac también ha sido acreditada a Vern Nolte de Automatic Tape Company4?5?), y comercialmente introducido en 1959 por Collins Radio en la Convención de la NAB de ese mismo año. El cartucho se usó a menudo en estaciones de radio hasta finales de la década de 1990, cuando predominaban formatos como MiniDisc y automatización de transmisión computarizados. | HISTORIA | El cartucho Fidelipac fue el primer cartucho de cinta de audio disponible comercialmente, basado en el diseño de cartucho de cinta de bucle sin fin desarrollado por Bernard Cousino en 1952, cuando Eash compartía un lugar en su tienda de electrónica, a principios de la década de 1950. En lugar de fabricar él mismo el formato Fidelipac después de desarrollarlo, Eash decidió otorgarle la licencia para su fabricación a Telepro Industries, en Cherry Hill, Nueva Jersey. Luego, Telepro fabricó y comercializó el formato con la marca Fidelipac | FUENTE : Fidelipac. in: Wikipedia. Disponible en : https://es.wikipedia.org/wiki/Fidelipac Acceso en : 27 nov. 2022

[ENG ] 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. Fidelipac is the official name of this industry standard audio tape cartridge. It was developed in 1954 by inventor George Eash (although the invention of the Fidelipac cartridge has also been credited to Vern Nolte of the Automatic Tape Company[4][5]), 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. | History: The Fidelipac cartridge was the first audio tape cartridge available commercially, based on the endless-loop tape cartridge design developed by Bernard Cousino in 1952, while Eash shared space in Cousino´s electronics shop in the early 1950s. Instead of manufacturing the Fidelipac format himself after developing it, Eash decided to license it for manufacture to Telepro Industries, in Cherry Hill, New Jersey. Telepro then manufactured and marketed the format under the Fidelipac brand name | Tape format
Fidelipac was originally a 1?4-inch-wide (6.4 mm) analog recording tape, two-track format. One of the tracks was used for monaural program audio, and the other being used for a cue track to control the player, where either a primary cue tone was recorded to automatically stop the cart, a secondary tone was recorded to automatically re-cue the cart to the beginning of the cart´s program material (in some models, two secondary tones, one after the program material, and one before it, were recorded to have the cart machine automatically fast-forward through any leftover blank tape at the end of a cart´s program), or a tertiary tone, which was used by some players to trigger another cart player or another form of external equipment. Later versions used three tracks, two for stereo audio, and the third for the cue track. | The standard tape speed for Fidelipac carts used in the radio broadcasting industry is 7.5 ips, although some cart players and recorders can be set to record at other speeds, such as 3.75 or 15 ips | SOURCE: https://en.wikipedia.org/wiki/Fidelipac

[ENG] Fidelipac | Fidelipac (1959 – late 1990s) | Fidelipac (commonly known as an NAB cartridge or simply ‘cart’) was a magnetic tape cartridge format, used in radio broadcasting for playback of material such as radio commercials or jingles. It was the first audio tape cartridge commercially available when it was introduced in 1959 by Collins Radio. | Fidelipac used ¼-inch endless loop tape, with two or three tracks one of which was used to cue the tape. Most players ran at 7.5 inches per second, though some could also run at 3.75 or 15 ips. | There were three sizes of Fidelipac available; the 4-inch wide A size (up to 10.5 minutes playing time), the 6-inch wide B size, and the 8-inch wide C size. The most commonly used for broadcasting purposes was the A size, and the B and C sizes were usually used for background music applications where the tape speed usually was 3.75 inches per second for longer playing times. | Fidelipac was adapted as the basis for the 4-Track Stereo-Pak cartridge. Other similar cartridge designs were later used in broadcasting, such as the Audiopak, Aristocart and Scotchcart. | Unlike the 8-Track cartridge (but like the 4-Track cartridge), the pinch roller was built into the player and swung into place through a hole in the cartridge. | Fidelipac was widely used at radio stations until the late 1990s, when such formats as MiniDisc and computerized broadcast automation made it obsolete. | SOURCE : MUSEUM OF OBSOLETE MEDIA.
