MR head manufacturing sensitivity analysis using transmission line model

Transmission line based equations are developed to describe the operation of MR heads. An analytical solution for magnetic flux in MR films is derived for linear operation. This transmission line method is used to analyze the design center of shielded dual stripe, soft adjacent layer and barberpole...

Zusammenfassung:Transmission line based equations are developed to describe the operation of MR heads. An analytical solution for magnetic flux in MR films is derived for linear operation. This transmission line method is used to analyze the design center of shielded dual stripe, soft adjacent layer and barberpole MR heads. Error propagation analysis is used to analyze the manufacturing tolerance sensitivity of these various heads. Finally, a Monte Carlo simulation is used to investigate the expected distribution in performance of manufactured MR heads.< >
