Dimafon is an abbreviation of "dictation magnetophone", a dictation device with magnetic recording that was used during the 1940's and 50's. It consisted of a spiral of steel wire embedded in a plastic disc. There were both one-sided and two-sided recordable solid magnetic discs, as well as flexible, one-sided recordable film. Besides its use as a dictation device, these audio recorders were also used for recording telephone conversations, automated announcements, or for recordings of radio broadcasts.
