8-track tape
8-track tape (formally Stereo 8: commonly known as the eight-track cartridge, eight-track tape, or simply eight-track) is a magnetic tape sound recording technology popular in the United States from the mid-1960s to the late 1970s when the Compact Cassette format took over.〔(【引用サイトリンク】quote=Just as the signs were all pointing to eight-track toppling vinyl as the format of choice for music lovers in the United States, Canada ''and to a lesser extent, in Great Britain,'' along came the audio cassette )〕〔(【引用サイトリンク】title=What Are 8-Track Tapes? )〕 The format is regarded as an obsolete technology, and was relatively unknown outside the United States, the United Kingdom, Canada and Australia.
Stereo 8 was created in 1964 by a consortium led by Bill Lear of Lear Jet Corporation, along with Ampex, Ford Motor Company, General Motors, Motorola, and RCA Victor Records (RCA). It was a further development of the similar Stereo-Pak four-track cartridge created by Earl "Madman" Muntz. A later quadraphonic version of the format was announced by RCA in April 1970 and first known as Quad-8, then later changed to just Q8.
== History ==
The original format for magnetic tape sound reproduction was the reel-to-reel tape recorder, first available in the US in the late 1940s, but too expensive and bulky to be practical for amateur home use until well into the 1950s. Loading a reel of tape onto the machine and threading it through the various guides and rollers proved daunting to some casual users—certainly, it was more difficult than putting a vinyl record on a record player and flicking a switch—and because in early years each tape had to be dubbed from the master tape in real-time to maintain good sound quality, prerecorded tapes were more expensive to manufacture, and costlier to buy, than vinyl records.
To eliminate the nuisance of tape-threading, various manufacturers introduced cartridges that held the tape inside a metal or plastic housing to eliminate handling. Most were intended only for low-fidelity voice recording in dictation machines. The first tape cartridge designed for general consumer use, including music reproduction, was the Sound Tape or Magazine Loading Cartridge (RCA tape cartridge), introduced in 1958 by RCA. Prerecorded stereophonic music cartridges were available, and blank cartridges could be used to make recordings at home, but the format failed to gain popularity.
