Zusammenfassung:A manufacturing method of a thin-film magnetic head, includes a step of forming many thin-film magnetic heads arranged along row and column directions on a wafer, each of the thin-film magnetic heads having a read head element, a write head element, and pairs of probe-use pads electrically connected with the read head element and the write head element, respectively, the pairs of probe-use pads being positioned so that at least part of each probe-use pad is removed by a cutting process along the row direction, a step of obtaining a plurality of row-bars by cutting the wafer along the row direction so that the at least part of each probe-use pad is removed, each of the obtained row-bars having the thin-film magnetic heads aligned in the row direction, a step of forming pairs of bonding pads electrically connected with the read head element and the write head element, respectively, on a surface opposite to an ABS of each thin-film magnetic head of each of the row-bars, and a step of cutting each row-bar along the column direction to separate into individual thin-film magnetic heads.
