Abstract: PROBLEM TO BE SOLVED: To provide a transducer suspension system provided with stuck electric leads. SOLUTION: This transducer suspension system has a transducer head, a lamination member and a load beam. The lamination member 112 is consisting of one support layer 158, at least two electric insulating layers 152, 156 and at least two conductive layers 150, 154. Respective electric leads are directly formed on the lamination layer so that they become directly above or under at least other one electric lead. Electric leads being at upper sides can perform the same noise cancellation as that of twisted pair lines. Moreover, it is possible to accommodate more numerous electric leads by the same suspension width by sticking the electric leads while providing spparations equivalent to a thickness D2 with respect to the minimum distance D1 to be needed in an etching processing. The insulating layer includes, for example, polyimide and the conductive layer can include, for example, copper. Further, a pattern can be formed by coating photoresist on the upper surface of the layer 150 and by exposing it with a light.
