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.

摘要： A heater member is formed in structure including a heater layer with a low electrical resistivity and a cap layer with a higher electrical resistivity, an electrically conductive electrode film is formed thereon, and electrically conductive bumps are formed thereon by plating. Unnecessary part of the electrode film is removed using the bumps as a mask. The heater member generates heat to thermally expand a thin-film magnetic head, whereby the distance is reduced between a recording medium and, a magnetoresistive device and/or an electromagnetic conversion device. During removal of the electrode film part of the cap layer with the higher electrical resistivity in the heater member is removed together with the electrode film, which reduces the variation in the total resistance of the heater member.
