摘要： 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.

摘要： A pole layer has a track width defining portion and a wide portion. The pole layer has: first and second side surfaces located opposite to each other in a first region extending from a medium facing surface to a position at a distance of 10 to 300 nm from the medium facing surface; third and fourth side surfaces located in a second region other than the first region; a fifth side surface located at the boundary between the first and second regions and connecting the first and third side surfaces to each other; and a sixth side surface located at the boundary between the first and second regions and connecting the second and fourth side surfaces to each other. The distance between the first and second side surfaces taken in the track width direction decreases with decreasing distance from the top surface of the substrate. The angle formed by the third and fourth side surfaces with respect to the direction orthogonal to the top surface of the substrate is smaller than that formed by the first and second side surfaces with respect to the direction orthogonal to the top surface of the substrate.

摘要： A method of manufacturing a magnetic head is disclosed. The steps of manufacture include the formation of an underlying layer made of a material whose etching rate of ion beam etching is higher than that of a magnetic alloy used to make a pole layer, and the formation of a magnetic layer, which includes a portion of the magnetic layer to be etched that will be formed into a track width defining portion by making its side surfaces sloped through etching. The magnetic layer is formed such that the portion to be etched is disposed on the underlying layer. The side surfaces of the portion to be etched by the ion beam etching are etched so that the magnetic layer is formed into the pole layer and so that the end face of the track width defining portion located in the medium facing surface has a width that decreases with decreasing distance from the substrate.
