Magnetic Recording Head

Description (Brief)
This “Red Head” recording-playback head was designed by Brush Company around 1950 for sale to tape recorder manufacturers. Inside the housing is a small, specially-shaped electromagnet designed to produce a focused magnetic field. When recording, a current fed into the head varied according to the strength of the input signal and that variation was captured by the recording tape. For playback, the magnetic field on the tape generated a signal in the head as it passed close. The closer the playback signal matched the input signal, the more accurate the recorded sound.
