摘要： A method of manufacturing a magnetic head includes the steps of: fabricating a magnetic head substructure by forming components of a plurality of magnetic heads on a substrate, the substructure including a plurality of pre-head portions aligned in a plurality of rows; and fabricating a plurality of magnetic heads by separating the plurality of pre-head portions from one another by cutting the substructure. In the step of fabricating the substructure, a plurality of sensors are formed, the sensors respectively showing individual sensor values corresponding to values of a plurality of different parameters each of which has an influence on characteristics of the magnetic head relating to a pole layer and each of which depends on the position of a medium facing surface. In the step of fabricating the magnetic heads, the medium facing surfaces are formed by lapping a surface formed by cutting the substructure so that a composite sensor value that depends on the plurality of individual sensor values shown by the plurality of sensors becomes a predetermined value.
