PURPOSE:To enable efficient reproduction even with a signal magnetic field of an extremely short wavelength by increasing the width of the part near the juncture of leads connecting to both ends of an MR elememt and forming a fine slit in proximity to the MR element so as to face said elememt. CONSTITUTION:Lead patterns 23, 24 consisting of conductors are connected to both ends 21, 22 of a magneto-resistance effect element (MR element) 20 and the parts 25, 26 near the juncture are widened in the width and an extremely fine slit S is formed therein in proximity to the element 20 so as to face the element. A magnetic field in the direction where the demagnetizing field is negated is generated in said space S. Reproducing efficiency is decreased by the demagnetizing field in the short wavelength signal magnetic field of high density recording where the change in the signal magnetic field is acute in the prior art but the effect of negating the demagnetizing field is generated by the formation of the slit S, by which the efficient reproduction is made possible even in the signal magnetic field of an extreme short recording wavelength. |
