Abstract

PURPOSE: To obtain a good characteristic throughout a range from a short wave length up to a long wave length at a reproducing operation time by regulating the distances between the surface of an MR element and the surface of a high-permeability material while relating this distance with a recording wave length in a structure where the MR element is held through a nonmagnetic layer by the high-permeability material.
CONSTITUTION: Electrodes 2 and 2' are connected to both ends of magnetroresistance effect element (MR element) 1 respectively. This structure is held between shield bodies 3 and 3' consisting of high-permeability materials through a nonmagnetic layer. In the structure above, surface distance g between MR element 1 and shield bodies 3 and 3' consisting of high-permeability materials is so controlled that a value obtained by dividing surface distance g by the shortest recording wave length on magnetic recording medium 5 may be within a range of 0.2 to 0.7.
