Material: Metal Size: 4" L x 2 1/2" W x 1 3/4" T ABOUT/HISTORY: Dictaphone was prominent in the provision of multi-channel recorders, used extensively in the emergency services to record emergency telephone calls (to numbers such as 911, 999, 112) and subsequent conversations. In the 1980s these recorders also started to be used in the financial industry to record conversations in dealing rooms. The recordings were made on reel-to-reel tape and could be located and replayed by date and time. By the late 1980s digital recording began to be offered as an alternative, and soon became the medium of choice. Additionally, Dictaphone at one point expanded its product line to market a line of electronic (desktop and portable) calculators. Late 1970s introduced new standard of Dictaphone magnetic tapes - mini cassettes, micro cassettes and pico cassettes. These smaller sizes of storage medium enabled the manufacturers to create truly small recording devices which were able to record as much as the previous non portable versions.
