ABSTRACT:
A magnetoresistive head includes a magnetoresistive effect element including a magnetoresistive film, which has a first ferromagnetic layer and a second ferromagnetic layer separated by a nonmagnetic layer. A magnetization direction of the first ferromagnetic layer is perpendicular to a magnetization direction of the second ferromagnetic layer when a signal magnetic field is zero. A pair of bias layers provide magnetic bias, and a top surface of each of the pair of bias layers faces a lower surface of each edge region of the magnetoresistive film. A pair of lead electrodes produce a current flow through the magnetoresistive film, and each of the pair of lead electrodes is disposed on or above the magnetoresistive film.
