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.

The pole layer incorporates a track width defining portion and a wide portion. The track width defining portion has an end located in a medium facing surface and defines the track width. The wide portion is coupled to the other end of the track width defining portion and has a width greater than the width of the track width defining portion. The value of NH×TH/WG is greater than zero and smaller than or equal to 0.85 μm, where NH is the distance from the medium facing surface to the boundary between the track width defining portion and the wide portion, WG is the space between the pole layer and the write shield layer taken in the medium facing surface, and TH is the distance from the medium facing surface to a point at which the space between the pole layer and the write shield layer starts to be greater than WG.
