Abstract:
A multi-channel thin-film magnetic head includes a substrate, a plurality of MR read head elements, a plurality of first resistive elements, and a second resistive element. Each MR read head element includes a lower magnetic shield layer, an upper magnetic shield layer, and an MR layer arranged between the lower magnetic shield layer and the upper magnetic shield layer. Each first resistive element has a first resistance value. One ends of the first resistive elements are connected to the lower magnetic shield layers or the upper magnetic shield layers of the MR read head elements, respectively. The second resistive element has a second resistance value that is higher than the first resistance value. One end of the second resistive element is commonly connected to the other ends of the plurality of first resistive elements. The other end of the second resistive element is grounded.
