When exogenous noise is applied to the ground wire of a thin film magnetic head, crosstalk noise occurs in a lead line and a ground lines located near the ground wire. Embodiments in accordance with the present invention avoid this by providing a common terminal near the central portion of a thin film head portion. Write element terminals are connected to lines extending from a coil. Read element terminals are connected to lead wires extending from electrodes of a GMR element. A heater terminal is connected to a line extending from a heater. The common terminal is connected to a ground line of upper and lower shields via a resistor, to ground lines of electrodes via other resistors and to a ground line of upper and lower magnetic pole pieces of a write element via another resistor. A ground line of a slider, a ground line of the heater, and a ground line of the common terminal are all connected to a ground terminal.
