ALBUMS IN FORGOTTEN FORMATS Inexpensive reel-to-reel tape recorders were widely used before the Philips "compact cassette", introduced in 1963, took over. Cassettes quickly displaced reel-to-reel recorders for consumer use. 8-track cartridge was an analog music recording format popular from the late 1960s to the early 1980s Between the 1960s and early 2000s, the compact cassette was one of the four most common formats for prerecorded music. [As an example this six track C cassette (UK 1983)] MiniDisc was announced by Sony in 1991 and introduced in January 1992. MiniDiscs were popular in Japan as a digital upgrade to cassette tapes, but have not been as popular world-wide. [Cohen's albums were released also in this format between 1994 and 2001] These items come from the collections of Dominique Boile and Jarkko Arjatsalo Texts from Wikipedia.
