the wire recorder
The next beast reviewed on our tour of the Jurassic Audio Park should
have been the Quad format...
But I completely fell in love with this machine, found in one of my Chicagoland friend's
cellar.
We all more or less heard about it : that the first magnetic audio recordings were
made on a steel wire... But it's the first time I laid my own eyes on one... and
in working condition, more than 50 years after it was manufactured !!!
First of all, the "thing" : This "Model 80" was manufactured by WEBSTER CHICAGO, in 1945, and was nicknamed an "Electronic Memory" (we're still far from a PC flash card !). It's a portable recorder, the top cover can stow several reels of wire as well as a microphone and connection cables.

Webster Chicago was famous in the forties with several recording machines and other Hi-Fi equipment in their catalog. On the left, a machine prior (?) to the Model 80. |
Now a bit of history : Magnetic recording was invented, depending on your ethical beliefs, by - Oberlin Smith (Brittish), who published a theoretical paper on the system in 1888. - Valdemar Poulsen (Danish), who built, in his early twenties, the first operational machine : the Telegraphon, in 1889. Doesn't that look furiously similar to the "Charles Cros / Thomas Edison" affair concerning the phonograph ? Who is the inventor, the scribbler or the builder ? |

But let's go back to wire recording and the
MODEL 80 !
I couldn't calculate the nominal spooling speed of the machine, but if I were to
guess (it spools much faster than I thought it would, hence a sound that's quite
good for that era !), I'd say it's about 30 ips.
The recording/playback head is mounted on a mechanism that slowly moves up and down.
The movement speeds up proportionaly when fast winding is engaged, that mechanism
is therefore certainly coupled to the take-up reel's (the big metal one) motor. Just as with fishing reels, the object is to get a uniform winding
on the entire height of the reel, so no overlaps can occur, which would inevitably
result in the wire breaking !

The microphone's look alone is worth a picture ! It seems it was taken
from a set on George Pal's War of the Worlds ! Note the connector which really deserves its own cage in the Jurassic Audio Park ! |
My friend's mother is also the proud owner of another machine of
the same era, which combines radio, phonograph and wire recorder ! The turntable
also doubles as the supply reel for the wire recorder. And you've guessed it, there
is a copy function from the record to the wire, making it the first copyright
infringment machine I know !
I'm waiting for the pictures which souldn't take long to get here...
