METHOD FOR CORRECTING A STATIC POSTURE OF A HEAD PORTION AND A STATIC POSTURE CORRECTING APPARATUS

摘要

A static posture correcting apparatus has a controller preparing a correction recipe-table, a measuring unit measuring a pitch angle and a roll angle of a head portion of a flexure of a head suspension, a laser irradiating unit irradiating laser beams on irradiation lines of a flexure of an objective head suspension, the controller selecting an effectual correction recipe from the correction recipe-table and controlling the laser irradiating section to irradiate laser beams on the irradiation lines of the flexure of the objective head suspension according to the selected correction recipe, wherein the controller considers variations among reference values of pitch angle and roll angle changes of the sample head suspensions when preparing the correction recipe-table and selects the recipe so as to diminish an expected variation in target static posture angle characteristic due to correction.
