Magnetic head and its manufacturing method

Abstract

Abstract PURPOSE:To reduce the assembling error in the final assembling process and to improve the reliability of a magnetic head by having the same block for an I- shaped core which prescribes the gap width of the core of an annular writing magnetic head and for a magnetic resistance sensor. CONSTITUTION:A reading head block is unified with an I-shaped core of a writing head together with a center shield by an adhesive, etc. The part of a size A is ground evenly so that a train of sensors 2 is set parallel to a reference surface D which is used for matching between the tentative height B of the sensor 2 and the tentative gap depth C of the writing head. Then the height B is measured, and a groove 13 is processed to obtain the prescribed depth C corresponding to the height B. Then blocks 16 and 17 are assembled and the head part is processed finally. In such a way, the assembling error of the final process is reduced with improvement of reliability for a magnetic head.
