TITLE OF THE INVENTION: Magnetic Head ABSTRACT OF THE DISCLOSURE: A magnetic head comprising a thin substantially U-shaped ferromagnetic sheet which is made of a material exhibiting magnetoresistance property and which is connected magnetically in at least one portion of a magnetic circuit having an air gap with the open end of the U-shaped ferro- magnetic sheet forming at least part of the air gap, and a pair of current electrodes or terminals attached to the ends of the thin ferromagnetic sheet for receiving current flow of a predetermined magnitude through the thin ferromagnetic sheet, whereby the variation in magnetic field across the air gap of the ferromagnetic sheet may be detected as the variation in voltage across the pair of current electrodes or terminals.
