Notes Durig the WW2 "The Brush Development Company" made this Navy Wire Recorder KS12016 which served as a basis for designs of other magnetic-recording equipment for various branches of the armed forces. This wire recorder is significant in that it was the first magnetic recorder where the recording medium was housed in a totally enclosed magazine. This magazine is attached to the portion of the instrument containing the drive motor and the amplifier section. The 750-r.p.m. motor is directly coupled to the take-up reel spindle during recording and reproduction. It has to be removed and rotated to engage the rewind spindle to the motor. A step-up gear in the magazine gives a rewind-forward ratio of 1.6 to 1. The magazine contains a ring-type recording head and solenoidal erasing head, together with a level-wind mechanism, elapsed-time indicator, and automatic stop. Electrical connections were made to the magazine by means of plug-type connectors. The recording medium is 0.006-inch 420-type stainless steel wire and its speed increased from a minimum of 5 ft. per sec. to a maximum of 7.5 ft. per sec. Mechanical brakes in the magazine tension the wire during operation and prevent unreeling while the magazine is removed.

This model was suggested by Ernst Erb.
