Advances in electronics in the 1930s, brought the first commercially available wire recorders to the market for use as dictating machines and telephone recorders.
Recordings were made on on solid steel media. This type of magnetic recording remained the only option outside Germany until about 1948. Considered the most significant of these devices, was the Blattnerphone or Marconi-Stille recorder. The steel tapes for this large recorder were 3 mm wide and the reel weighed 15 kg.
In 1933, the Canadian Radio Broadcasting Commission (later CBC) installed three Blattnerphones in the Château Laurier Hotel in Ottawa where they had a station. Significant events such as royal and political addresses, the opening of Parliament could be recorded live for rebroadcast later to reach the widest possible audience.
In 1969, the CBC donated a Blattnerphone with 11 reels of tape to the Canada Science and Technology Museum. In 1992, the Museum shipped its Blattnerphone recordings to Telecom Australia in Melbourne, where technicians played them back for the first time in fifty years. Video
