Abstract
A magnetoresistive sensor and preamplifier system has an excess differential imbalance detector, (a) for detecting magnitude differences between a pair of signals occurring at the output of a preamplifier subsystem due to modal transitions, and (b) for initiating action to overcome same. The excess imbalance detector changes a threshold therein to become more sensitive to smaller imbalances in the output signals being monitored after detection of a modal transition imbalance.
