ABSTRACT:
A magnetoresistance effect type thin film magnetic head comprising an MR element with electrodes provided at a fore end and a rear end thereof in the direction to confront a magnetic recording medium, wherein the electrode at the fore end of such MR element is electrically connected to a shielding magnetic layer to thereby eliminate any electrical instability at the fore end of the MR element, hence averting the characteristic instability in a playback mode while minimizing the unsteady generation of noise. The thin film magnetic head further comprises a first conductor having a great capacity and disposed in the proximity of the MR element, and a second conductor having a capacity smaller than that of the first conductor and connected to the fore-end electrode of the MR element. Such first and second conductors are connected to respective ground potentials independently of each other, thereby averting breakdown of the magnetic head that may otherwise be caused by the static charge generated due to the rotation of the magnetic recording medium during the operation.
