Abstract
A technique to perform a guided partial response target search for characterizing a read channel of a disk drive. A target adaptation scheme pre-selects a plurality of targets from a pool of potential targets based on certain criteria and the selected targets are sorted in linear gradient orders. When target adaptation is being performed by comparing the equalizer output with an ideal reconstructed signal, a difference value sets a gradient vector that is used to determine which direction to move along the sorted list of targets to select the next target.
