Abstract
A system for calibrating a magneto-resistive (MR) head includes a biasing circuit and a calibration module. The biasing circuit generates a first current to bias a first head during a calibration mode and a calibrated current to bias the MR head during an operating mode. The calibration module calibrates the first current during the calibration mode by adjusting the first current using nonlinear steps to determine the calibrated current.
