Abstract
A non-contact sensor system according to one embodiment includes a substrate having a substantially planar surface with at least one sensor element mounted to the substrate, the at least one sensor element being directed by a guiding element towards at least one data track on a substantially planar medium positioned opposite the at least one sensor element, wherein the substantially planar surface of the substrate and the substantially planar surface of the medium each carry at least one magnetic track, wherein orientations of magnetizations of the magnetic tracks are such that the substrate experiences a force away from the medium.
