Disk drive comprising stacked and stepped traces for improved transmission line performance

摘要

A disk drive is disclosed comprising a disk, a head actuated over the disk, a preamp, and an interconnect for coupling the head to the preamp. The interconnect comprises a first transmission line stacked over a second transmission line, and a dielectric between the first transmission line and second transmission line. A shape of the first and second transmission lines varies along a length of the interconnect such that the interconnect comprises an approximation of an inductor/capacitor ladder network.
