Abstract:
1. A method for correcting a static posture of a head portion, the head portion constituting a flexure to be attached to a head suspension for supporting a slider, the method comprising steps of: preparing a correction recipe-table based on reference values of static posture angle changes obtained from head portions of flexures of a plurality of sample head suspensions by irradiating laser beams on a plurality of objective portions of each head portion; measuring a static posture angle of a head portion of a flexure of an objective head suspension to be corrected; selecting an effectual correction recipe instructing required portions of the flexure of the objective head suspension on which laser beams are irradiated from the correction recipe-table based on measurement value of the measured static posture angle; and irradiating laser beams on the required portions of the flexure of the objective head suspension according to the selected correction recipe so as to correct the static posture angle of the head portion of the flexure of the objective head suspension, wherein the correction recipe-table is prepared in view of variations among the reference values of the static posture angle changes of the sample head suspensions, and the correction recipe is selected in such that an expected variation due to correction is diminished to obtain target static posture angle characteristic of the head portion of the flexure of the objective head suspension.
