New Magnetic-Recording Head

A three-pole magnetic head produces a magnetic field at the recording gap which is more uniform throughout the thickness of the magnetizable layer, and decays more rapidly at the trailing edge. With this head, optimum bias is practically the same for high as for low audiofrequencies. High audio-frequencies are recorded at a 3-db to 7-db higher output level before distortion as compared with a similar head of conventional design.
