Method of manufacturing a magnetic head with an MR element

A method of producing a magnetic head which includes an MR element and a permanent magnet for applying a bias magnetic field to the MR element, comprising the steps of:

• (a) providing a thin sheet of metal;
• (b) shaping said sheet in a predetermined pattern to produce a lead frame having an MR element mount section for mounting said MR element, a magnet mount section for mounting said permanent magnet, lead connecting sections to be electrically connected to said MR element, and tape-contact sections with which a magnetic tape is to make contact;
• (c) bending said tape-contact sections perpendicularly to a general plane of said lead frame;
• (d) placing said MR element in said MR element mount section such that a tape-contact surface of said MR element is flush with said tape-contact sections of said lead frame;
• (e) placing said permanent magnet in said magnet mount section;
• (f) electrically connecting said lead connecting sections of said lead frame to connecting sections of said MR element;
• (g) placing said frame in an assembled condition in a metal mold and pouring synthetic resin into said metal mold such that said tape-contact surface of said MR element and said tape-contact surfaces of said lead frame are exposed to the outside and end portions of said lead connecting sections of said lead frame extend to the outside, thereby embedding said lead frame in the synthetic resin;
• and
• (h) finishing a molding of the synthetic resin to a predetermined contour of said magnetic head.
