A Magnetic Sound Recorder of Advanced Design

R. J. Tinkham, J. S. Boyers

Recent developments in magnetic recording have led to practical use of this art as a high-fidelity recording system. The particular apparatus described is the result of a need for wire recording equipment of professional caliber. It is characterized by good frequency response, low distortion, freedom from “wow” and flutter, and lock-in synchronous drive. The electrical and electromagnetic portions are the result of experience gained by research during the war. The mechanical portions have many parallels in motion picture equipment design. This apparatus is suitable for many motion picture recording applications.
