After the invention of paper tapes coated with magnetic powder in 1928, AEG and BASF launched a joint venture in order to develop a tape recording system. Stepwise improved between 1931 and 1934, AEG presen-ted 1935 the model K2, named "Magnetophon" together with the acetyl cellulose tape type "C" of BASF. 1940, AC-biasing in model K4 improved the signal to noise ratio up to 60 dB, surpassing all known recording systems at that time. The steps of development until the 1950th will be presented in detail.
