    • A magnetoresistive head for detecting a magnetic signal on a recording medium as a reproduction signal includes a first magnetic shield, a first electrode terminal disposed on the first magnetic shield, a magnetoresistive film disposed on the first electrode terminal, magnetic domain control films disposed on both sides of the magnetoresistive film for controlling magnetic domains in the magnetoresistive film by applying a bias magnetic field in a first direction to the magnetoresistive film. The magnetoresistive head further includes a second electrode terminal disposed on the magnetoresistive film, and a second magnetic shield disposed on the second electrode terminal. At the time of reproduction of the magnetic signal, a sense current is passed across the first and second electrode terminals in the direction perpendicular to the film plane of the magnetoresistive film so that the direction of a current magnetic field in a medium-opposed end portion of the magnetoresistive film is in the first direction.
    • 用于检测作为再现信号的记录介质上的磁信号的磁阻头包括第一磁屏蔽,设置在第一磁屏蔽上的第一电极端子,设置在第一电极端子上的磁阻膜,设置在两者上的磁畴控制膜 用于通过向磁阻膜施加第一方向的偏置磁场来控制磁阻膜中的磁畴的磁阻膜的侧面。 磁阻头还包括设置在磁阻膜上的第二电极端子和设置在第二电极端子上的第二磁屏蔽。 在再现磁信号时,感测电流在与磁阻膜的膜平面垂直的方向上穿过第一和第二电极端子,使得中间相对端部中的电流磁场的方向 磁阻膜位于第一方向。
