PROBLEM TO BE SOLVED: To highly accurately manufacture an assembly having plural magnetic heads at a low manufacturing cost. SOLUTION: A sub-assembly having magnetic pole pieces 621 , 622 , separated from each other through a gap is formed on a base material 60 and magnetic pole pieces 721 , 722 separated from each other through a gap and magnetic connectors 741 , 742 arranged in parallel with them and consisting of a magnetic material are formed on a base material 70. In order to secure magnetic continuity, one of the base materials 60, 70 is inverted and combined with the other base material so that the connectors 741 , 742 on the base material 70 are brought into contact with the pieces 621 , 622 on the base material 60, and then the base material 70 is thinned until the pieces 721 , 722 , and the connectors 741 , 742 are exposed. A magnetic circuit for mutually connecting the connectors 741 , 742 , a reading/writing means magnetically connected to the magnetic circuit, a magnetic circuit for mutually connecting the pieces 721 , 722 , and a reading/writing means magnetically connected to the magnetic circuit are formed on the thinned base material 70. |
