摘要：

This paper describes the design and performance of yoke-type read heads with spin-dependent tunneling magnetoresistive (TMR) elements. Magnetic field calculations have been carried out for a yoke-type TMR head with a front-stacked gap (Front-SG). The head has the advantage of a higher signal-to-noise ratio than that of a shielded TMR head and produces Lorentzian waveforms without any distortion in combination with perpendicular magnetic recording media.
