Dictating Machines to Use Magnetic Tape (Oct, 1934)
Dictating Machines to Use Magnetic Tape
With the development of the steel tape method of sound recording, present day dictaphones may soon become obsolete. In demonstrations at the Century of Progress sound was stored in the magnetic ribbon for only a few seconds, but engineers believe it possible to construct a simplified dictating machine set along similar lines.
With the use of large rolls of the steel tape, there would be no need to change records as frequently as in the present apparatus. Court proceedings could be stored indefinitely.
