Cartridge Wire Recorder

Description (Brief)
This model MI-12525 RCA wire recorder shows one answer to a major problem of using steel wire to record sound. The recording wire is wound into a cartridge. The user simply inserts the cartridge into the recorder and can quickly begin using the machine. This machine was designed for use in office dictation around 1948.
Early magnetic recorders used steel wire or steel bands as a recording medium instead of plastic tape. Steel wire was fragile and tangled easily. Threading a recording machine took a certain amount of finesse and the wire could easily break if mishandled.
