Abstract:
1. A manufacturing method of a head gimbal assembly, comprising the steps of: preparing a five-layer sheet which includes a first metal thin-plate layer made of a stainless steel thin plate, a first resin layer laminated on said first metal thin-plate layer, a second metal thin-plate layer made of a stainless steel thin plate and laminated on said first resin layer, a second resin layer on said second metal thin-plate layer, and a conductive layer laminated on said second resin layer; forming a multilayer suspension by partially removing at least part of layers of said five-layer sheet, said multilayer suspension comprising a resilient bending section, a resilient gimbal section for mounting a head slider and a rigid section for coupling said bending section and said gimbal section, wherein said resilient bending section and said resilient gimbal section are each formed by partially removing at least said first metal thin-plate layer and said rigid section is formed by partially removing at least one of the second resin layer and the conductive layer; and fixing the head slider having at least one head element on said gimbal section of said multilayer suspension.
