摘要： A method of manufacturing magnetic heads comprises the steps of: fabricating a magnetic head substructure by forming components of a plurality of magnetic heads on a single substrate so that 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. Indicator sections are formed in the substructure. The indicator sections include first indicators and second indicators. Widths of the first and second indicators are equal in an imaginary surface indicating a target location of the medium facing surfaces. One of the widths of the first and second indicators decreases while the other increases with shifts in position along the direction orthogonal to the medium facing surfaces.

摘要： A method of forming a magnetic head comprises the steps of: selectively exposing through the use of a photomask a photoresist layer unpatterned; forming a pattern for forming a pole layer by developing the photoresist layer after the exposure; and forming the pole layer through the use of the pattern. The photomask includes first to third regions. The first region has such a perimeter that a projection image thereof is shaped along a perimeter of an ideal shape of the top surface of the pole layer. The second region touches the perimeter of the first region, and is located outside the first region. The third region is located inside the first region without touching the perimeter of the first region. The third region suppresses deviation of the pole layer from its desired shape which may be caused by the effect of light reflected while the photoresist layer is exposed.

摘要： A method of manufacturing magnetic heads comprises the step of: fabricating a magnetic head substructure by forming components of a plurality of 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 substructure first resistor elements and second resistor elements are formed. Each of the first resistor elements has a resistance that varies depending on the location of an end of an MR element located in a medium facing surface along the direction orthogonal to the medium facing surface. Each of the second resistor elements has a resistance that varies depending on the location of an end face of a track width defining portion located in the medium facing surface along the direction orthogonal to the medium facing surface. The medium facing surfaces are formed while monitoring the resistance values of the first and second resistor elements.

摘要： The system includes a magnetic head which faces a recording medium. The magnetic head has a coil which generates magnetic fields. The magnetic head also has a pole layer which is formed using a pattern. The pole layer allows magnetic flux generated by the coil to write data onto the recording medium. The pole layer generates a write magnetic field for writing data onto the recording medium.A photomask is used to form the magnetic head. The photomask includes three regions. The first region has such a perimeter that a projection image thereof is shaped along a perimeter of an ideal shape of the top surface of the pole layer, and the second region touches the first region's perimeter. The third region suppresses deviation of the pole layer from its desired shape which may be caused by the effect of light reflected while the photoresist layer is exposed.
