AbstractA micromagnetic model is performed to find the proper geometrical and magnetic parameters for current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) spin-valve heads at higher recording densities. The readout signals were studied versus the various height to width ratios for GMR sensors. When the GMR sensor width is reduced to 40 nm, the magnetization of the free layer rotates coherently in response to the excitation fields at various height to width ratios. In the calculated transfer curve of the GMR heads, the geometry and remanent M-r delta of the hard magnetic bias layers are optimized for the good performance characteristics of the head signal output. The imaging effects related to the narrow-gap shields are also investigated for the head design.
