Abstract
A disk drive is disclosed. The disk drive comprises a disk, a head configured to write data to and read data from the disk, and an actuator configured to position the head relative to the disk. The disk drive also comprises a die including internal circuitry electrically coupled to the head and a bypass trace electrically coupled to the actuator, wherein the internal circuitry comprises one or more preamplifiers and the bypass trace is electrically isolated from the internal circuitry.
