Thin-film magnetic head having ensured insulation between shield and magnetic detecting element
A thin-film magnetic head has a lower shield layer and an upper shield layer which are each composed of two layers of a first shield sub-layer and a second shield sub-layer. The second shield sub-layer has a specific resistance higher than that of the first shield sub-layer. Thus, even though the gap length become shorter, the second shield sub-layers and gap layers ensure electrical insulation, and therefore, an electrically insulative thin-film magnetic head can be achieved.
