PURPOSE:To prevent a noise signal from generating in a coil even when a conductive recording medium being at an earth potential and a magnetic pole are brought into contact with each other by having a conductor providing a connecting part whose one edge is connected to a magnetic pole and the other edge is connected to a lead wire for grounding from an external part or providing part connecting to a lead wire for grounding at a part of the magnetic pole. CONSTITUTION:A title thin film magnetic head is composed of a magnetic pole 3, a coil 5, a drawing pattern 6 for a coil, a terminal 7 for a coil, a substrate 8 and an insulating film 9. At such a time, a terminal 2 for magnetic pole ground is provided adjoining to the terminal 7 for the coil and a drawing pattern 1 for magnetic pole ground is electrically connected to the magnetic pole 3. Thus, by grounding the magnetic pole, the electrification of the magnetic pole can be prevented, and even when the conductive recording medium, which is used as the magnetic pole and the earth potential is brought into contact with each other, a noise signal does not occur in the coil. |
