Abstract

Although there have been many attempts to use high-sensitivity magneto-resistive (MR) heads in perpendicular magnetic recording, their readback resolution not high enough, because of their large shield gap length. are We describe MR head that has a high D₅₀ of 270 kFRPI with a narrow shield gap associated with a differential equalizer, The S/N ratio of the equalized signal is also investigated.
