Abstract

PURPOSE: To improve resolution and an indefective product rate by using a permanent magnet small piece, which is arranged in a part outside the gap interposed between a shield and a magnetoresistance effect element, as a DC bias magnetic field applying means.
CONSTITUTION: Shields 3 and 4 consisting of high-permeability magnetic substances are formed on substrate 2 so that shields 3 and 4 may interpose magnetoresistance effect element 1 which consists of a ferromagnetic substance thin film and has read conductor terminal 6 at both edges. Gaps g1 and g2 which insulate magnetically shields 3 and 4 and element 1 is formed by non-magnetic electrical insulator. Further, small piece 7 of a permanent magnet having the magnetization direction of the y axis direction previously is arranged on substrate 2 where a magnetoresistance effect head with shields shoul be formed. This head is arranged vertically near magnetic storage medium having magneticzation direction 8.
