Crosstalk from a write signal on wiring on a suspension needs to be reduced since an ESD withstand voltage is decreased due to high sensitivity of a GMR head. In one embodiment, a terminal arrangement on an element-forming surface of a magnetic head slider consists of a ground terminal G, a read terminal R+, a read terminal R-, a write terminal W+ and a write terminal W- in order from the outside. With this terminal arrangement, the wiring order on a suspension consists of a read wire R-, a read wire R+, a ground line G, a write wire W- and a write wire W+ in an arrangement unlike the terminal arrangement. In other words, the ground line G is interposed between the write wires W and the read wires R. In this way, the wiring of the write wire W and the wiring of the read wire R are never arranged adjacently to each other, and further, the ground line G is interposed between the write wires W and the read wires R, thereby reducing crosstalk on the read wires R caused by a writing current with a high frequency which flows in the write wires W.
