摘要： A magnetoresistive effect element includes a laminated body including a magnetosensitive layer a magnetizing direction of which is changed by an external magnetic field and constituted such that a current is made to flow in a direction orthogonal to a laminated layer face thereof, and a annular magnetic layer arranged at a side of one face of the laminated body to constitute an axial direction by a direction along the laminated layer face and constituted to be penetrated by a plurality of lead wires and therefore, a closed magnetic path can be formed by making current flow to a plurality of lead wires and inversion of magnetization at the magnetosensitive layer can further efficiently be carried out.

摘要： A thin film magnetic head includes a slider and thin film magnetic transducers, the slider supporting the thin film magnetic transducers. At least one of these thin film magnetic transducers is a magnetoresistive read element. The surface resistivity .rho. of the magnetic film of the magnetic disk is within the range of .rho..gtoreq.0.03.OMEGA..multidot.cm. Electric leak from the thin film magnetic head to the magnetic disk and electric discharge between these two are prevented.
