Stereo 8, commonly known as the eight-track cartridge, eight-track tape, or simply eight-track, is a magnetic tape sound recording technology. It was popular in the United States from the mid-1960s through to the early 1980s, but aside from a brief early period of moderate popularity in the UK was relatively unknown in many European countries.
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.(Adapted from Wikipedia)
But the DDDBMT tape is not an 8 track, but a 4 track, as we learned from Johnny Owens through our guestbook. He wrote: “Just a little correction (I’m always full of corrections): the “Time to Take Off” US tape cartridge shown is NOT an 8-track cartridge. It is the forerunner of the 8-track, known as a 4-track (notice the “4″ on the spine of the tape) or Stereo-Pak cartridge. 4-track cartridges (article available at https://en.wikipedia.org/wiki/Stereo-Pak ) were available in the U. S. mostly during the 1960s (hence the time frame for that particular DDDBMT album) and ceasing production in 1970, sharing limited popularity along with reel-to-reel (also known as open-reel) tapes during that time period. (Of course, LPs and 45s were the predominant U. S. media throughout the pre-CD era.) Cassettes were also becoming popular in the late 1960s, with 8-tracks taking a lead in the U. S. in the 1970s, and cassettes gaining a larger U. S. market share in the 1980s before the widespread proliferation of the CD.”
