An early example of recording is the wire recorder, this machine dates from
1942 and was built by Boosey & Hawkes, this model is called the Wirek type A.
This recorders design is primarily for speech recording, designed to be portable
(57lb), it uses G.73 Boosey & Hawkes stainless steel 0.004" low coercively
austenitic steel recording wire , wound on a standard 3. 3/4 inch diameter
spool. As the wire winds from one reel to the other, two arms close to the reels
move up and down on a clockwork mechanism to ensure the wire is fed onto the
reels evenly to prevent snags which lead to the wire breaking. This machine
records at two speeds, the lower being 30 ips and the higher being 60 ips giving
66 or 33 minuets recording time respectively, a future on this recorder is a
timer stop, the machines counter has a second rotor control which when set and
reached by the wire counter will shut the recorder off.
