Magnetic tape sound recording in the context of Cassette tape (format)

Super 8 mm film is a motion-picture film format released in 1965 by Eastman Kodak as an improvement over the older "Double" or "Regular" 8 mm home movie format. The formal name for Super 8 is 8-mm Type S, distinguishing it from the older double-8 format, which is called 8-mm Type R. Unlike Super 35 (which is generally compatible with standard 35 mm equipment), the film stock used for Super 8 is not compatible with standard 8 mm film cameras.

The film is nominally 8 mm wide, the same as older formatted 8 mm film, but the dimensions of the rectangular sprocket hole perforations along one edge are smaller, which allows for a larger image area. The Super 8 standard also allocates the border opposite the perforations for an oxide stripe upon which sound can be magnetically recorded.

The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound-recording technology that was popular from the mid-1960s until the early 1980s, when the compact cassette, which antedated the 8-track system, surpassed it in popularity for recorded music.

The format was commonly used in cars and was most popular in the United States and Canada, and to a lesser extent, in the United Kingdom, Ireland, and Japan. One advantage of the 8-track tape cartridge was that it could play continuously in an endless loop, and did not have to be ejected, turned around, and reinserted to play the entire tape. After about 80 minutes of playing time, the tape would start again at the beginning. Because of the loop, no rewind is needed. The only options the user has are play, fast forward, record, and program (track) change.
