Abstract: PROBLEM TO BE SOLVED: To provide a magnetoresistive effect head embodying multitracking with which recording and reproducing operation under a low flying height or sliding with high sensitivity and low noise is possible and higher density and higher speed are possible. SOLUTION: The magneto-resistive head of a yoke structure comprises a set of magnetic yokes (2, 7f, 7r) having gaps (4, 5) with which a prescribed reproduction resolution is obtainable, an anisotropic magnetoresistive effect element (AMR) 8 or giant magneto-resistive effect element (GMR) which is installed near the thinly formed part of these magnetic yokes, leading-out conductors (9, 10) for energizing either of these magneto-resistive effect elements (MRs) and a conductive 6 for bias magnetic field application to the magneto- resistive effect element 8 according to need. At this point, the magneto-resistive effect element 8 is arranged in contact with the magnetic yokes (7f, 7r) or in sufficient proximity to the distance below 100 nm. The plural magnetic heads are so arrayed in such a manner that the distance between the adjacent tracks attains
