Abstract:
A method of manufacturing a head suspension includes a punching process, a positioning process, and an affixing process. An objective part on the head suspension to which a damper 73 is affixed includes a discontinuous section 72. The punching process punches a damper material into the damper 73 whose shape corresponds to the shape of the objective part excluding the discontinuous section 72. The positioning process positions the damper 73 to the objective part so that the damper 73 avoids and surrounds the discontinuous section 72, and the affixing process affixes the damper 73 to the objective part. The method secures a uniform damping effect among manufactured head suspensions and improves the yield of dampers and head suspensions without deteriorating the functions and performances of the head suspensions.
