摘要： A method is presented for grinding a surface of an elongate bar having a plurality of thin film magnetic elements aligned in a line, each of the thin film magnetic elements having a magnetoresistive sensor for reading a magnetic record from a recording medium and an inductive electromagnetic transducer for writing a magnetic record into the recording medium in a stacked structure, the surface of the bar being a grind surface so that it can be formed into an air-bearing surface by means of the grinding. The method has steps of providing first resistive films on the grind surface in advance along a first longitudinal line parallel to a longitudinal direction of the bar, and providing second resistive films on the grind surface in advance along a second longitudinal line parallel to the longitudinal direction of the bar. The method further has a step of grinding the grind surface while pressing the bar against a rotating grinding disc with the longitudinal direction of the bar positioned toward a radial direction of the grinding disc, measuring electric resistance values of the first and second resistive films, and controlling an amount that is ground of the grind surface in the longitudinal direction and a direction perpendicular to the longitudinal direction based on the electric resistance values of the first resistive film and the second resistive films.

摘要： In the head slider of the present invention, recording and reproducing electrode pads and heater electrode pads are attached to the same surface of an overcoat layer. The heater electrode pads are located on both sides of a group constituted by the recording and reproducing electrode pads. As a consequence, leads for the heater are located between respective leads for recording and reproducing head parts, whereby crosstalk can be prevented from occurring between the leads for the recording and reproducing head parts.

摘要： The heaters in the respective thin-film magnetic head in the bar are electrically connected to its neighbors, and a variable resistor is connected to each of the heaters in parallel. The resistance of each of the variable resistors is varied depending on the amount that the medium-opposing surface (ABS) of the thin-film magnetic head is to project. Also, the medium-opposing surface of the thin-film magnetic head in the magnetic head bar is polished while energizing all the heaters by the same power supply.
