摘要：
A suspension comprises a flexure and a plurality of electrical traces. The flexure has a leading portion and a tailing portion, and has a laminated structure comprising a substrate layer, a dielectric layer, and a grounding layer sandwiched therebetween. The electrical traces comprise at least one pair of write traces, each write trace has a bonding pad positioned on the leading portion, a terminal pad positioned on the tailing portion, and a write wire connecting the bonding pad and the terminal pad, the write wire has at least one portion being furcated into at least two sub wires. The present invention can lower the impedance and decrease the signal transmission loss, and widen the frequency bandwidth simultaneously. The invention also discloses a HGA and a disk drive unit.
