PURPOSE: To improve productivity without allowing the residual part of a core to remain by providing a cut surface on a head block in such a manner that the joining width of a slider block with a core block is the same as the core width on a medium-facing surface side and is the same as the width of the slider block on the opposite side thereof.
CONSTITUTION: The head block formed by joining the core block 11 and the slider block 11 via a nonmagnetic material to constitute a magnetic gap is so formed that the joining width of the slider block 10 with the core block 11 is the same as the core width CW on the side 11b to be the medium-facing surface side. The cut surface inclined with the gap-facing surface is provided on the head block at the same width as the width S 2 of the slider block 10 on the opposite side 11a thereof. The residual core part is simultaneously removed in this way at the time of cutting the core block 11 to the prescribed core width. The workability is thus improved.
