A flex circuit including a multiple layer structure is disclosed. The multiple layered structure includes a first or top layer and a second or base layer. Top traces and bond pads are fabricated on the top or obverse layer and interlayer traces and bond pads are fabricated between the first and second layers to provide an electrical interconnect to electrical components on a head assembly. In an illustrated embodiment, the flex circuit includes portions including the first or base layer and the second or top layer and one or more reduced thickness portion including the first or base layer and not the second layer. In one embodiment, the gimbal portion of the flex circuit includes the first layer and not the second layer of the multiple layer structure and in another embodiment a bending portion of the flex circuit includes the first base layer and not the second layer of the multiple layered structure to provide a reduced thickness to facilitate bending, for example in a micro-actuation region of the load beam.
