Suspension with divided positive and negative write trace sections, and head gimbal assembly and disk drive unit with the same
A suspension includes a positive write trace and a negative write trace. The positive write trace is separated into at least two positive write trace sections located at two different layers respectively, and the negative write trace is separated into at least two negative write trace sections located at two different layers respectively. Each positive write trace section and each negative write trace section are alternately arranged along a longitudinal direction on two different layers, and the positive write trace sections at different layers are connected together via conductive crossovers, and the negative write trace sections are connected together via conductive crossovers. The present invention can obtain balanced propagation time in the stacked trace structure to reduce signal distortion, and obtain widened frequency bandwidth.
