Magnetic head with helical coil and plural outer conductor groups and method of manufacturing same
The magnetic head in accordance with the present invention comprises first and second magnetic pole layers, a link part for magnetically linking the first and second magnetic pole layers, and a thin-film coil helically wound about at least one of the first and second magnetic pole layers. The thin-film coil comprises a plurality of inner conductor parts arranged in parallel with each other with an insulating film interposed therebetween, a plurality of first outer conductor parts located on the side of the first or second magnetic pole layer opposite from the side where the inner conductor parts are located, a plurality of second outer conductor parts located on the side of the first outer conductor parts opposite from the side where the inner conductor parts are located, and a plurality of connecting parts for connecting their corresponding inner conductor parts and first and second outer conductor parts.
