The  magnetic paper tape was invented in 1922, but it took until 1928 when 
the  inventor, Fritz Pfleumer, could present a workable machine and impress 
the  public so that AEG bought his patent. 
Same year, 1928: Karl Bauer's first  magnetic cassette recorder (used 
mainly for taping phone conversations)  

1933: the 'Texophon' by C.Lorenz Gesellschaft, Berlin (for radio  remote 
recording) 
1935: The C.Lorenz Gesellschaft, Berlin, introduces the  
'Stahltonmaschine', also for remote recording; AEG then developed the plastic  tape (1935).
