Production of magnetic head

Abstract

Abstract PURPOSE:To increase the mechanical strength of a glass joint part consisting of a non-magnetic material on a gap abutting face and to prevent a winding member from being broken by external force by setting up the width of the non-magnetic material to a value wider than that of the winding member. CONSTITUTION:The width l+DELTAl of glass 14 consisting of the non-magnetic material is set up so as to be wider than the width l of a C core block 12 and reinforced by a glass part 14c and a part 14d of the glass 14 is embedded in the side of a slider block 11. Thereby, mechanical strength, i.e. deflective strength, is increased. Even if external force is applied from the side of the C core block 12 at the time of winding, ultrasonic washing, etc., in case of mechanical working of a magnetic head, the C core block itself can be previously prevented from being broken. Since the width DELTAl of the reinforcing glass part 14c is suppressed to the width DELTAl equal to the width l1 of filled glass having strength necessary for the production of a magnetic head, the influence of core deformation or magnetic distortion due to the stress of glass to be a non-magnetic material can be reduced and magnetic characteristics can be prevented from being deteriorated at the time of increasing the quantity of glass.
