Abstract:
A disk drive comprising a disk, and a head actuated over the disk, the head comprising a read element and a write element. The disk drive further comprises a preamp and an interconnect comprising a first transmission line and a second transmission line coupling the head to the preamp. A compensation network is disclosed operable to compensate for an impedance discontinuity in the first and second transmission lines, the compensation network comprising a first trace and a second trace connected in parallel with the first and second transmission lines, wherein a shape of the first and second traces varies to form at least a first capacitor.
