摘要：
The present invention relates to the structure of a magneto-resistive head for reducing the spike noises generated in the head and for increasing the signal to noise ratio when the information is reproduced. In order to achieve the object, an electric conductor layer is disposed at both sides or one side of a magneto-resistive element, and the conductor layer is isolated from the element and connected to a DC potential.
