Abstract
Disclosed herein are suspension assembly structures for data storage devices that include physical or virtual crossovers of the pairs of differential signal traces to improve immunity to crosstalk and other interference. In an embodiment, the suspension assembly structure comprises a first trace for carrying a first component of a current to a differential transducer on a slider, a second trace for carrying a second component of the current to the differential transducer on the slider, and third and fourth traces for providing a differential write current to a writer of the data storage device, wherein the first trace physically crosses over the second trace at a first distance from a tail of the suspension assembly structure.
