Abstract
A method of manufacturing magnetic heads comprises the step of: fabricating a magnetic head substructure by forming a plurality of components of the magnetic heads on a single substrate, wherein a plurality of rows of pre-head portions that will be the respective magnetic heads later are aligned in the substructure; and fabricating the magnetic heads by separating the pre-head portions from one another through cutting the substructure. In the step of fabricating the substructure, a plurality of indicators are formed, each of the indicators serving as a reference for indicating the location of a region ABS in which the medium facing surfaces of the magnetic heads are to be formed.
