Wire Recording Cartridge

<< >>
Description (Brief)
One of the difficulties of using steel wire as a recording medium was the fragility of the thin wire. These RCA model MI-12877 recording cartridges from about 1948 were designed to address that problem. The user simply inserts the cartridge into the recorder and can quickly begin using the machine. The steel casing is durable and the wires are only exposed at the front of the cartridge.
