|JFK at UCLA: Nov. 2, 1959|
Some background: Various recording technologies were in use in the early 1960s. Tape and wire recorders were introduced in the period after World War II. (Germany had made advances in magnetic recording which were captured as part of the American invasion and then made available to U.S. manufacturers.) But there were other needle-in-groove technologies used for dictation machines that co-existed for a time with magnetic recording. Among them was the Dictaphone Dictabelt machine which recorded on rotating plastic cylinders and was an updated version of the older Edison Ediphone. (Google "Ediphone" if you are unfamiliar with those machines.) When the White House tapes were discovered as part of the Nixon Watergate affair, it was later revealed that there had been similar recording under Johnson and Kennedy. Those earlier administration recordings are now available.
