ABSTRACT:
A non-contact magnetic sensor system according to one embodiment includes a substrate and a magnetic medium spaced from the substrate and having a data track thereon. A sensor element is mounted to the substrate. A guiding element biases the substrate towards the magnetic medium. A first magnetic track is positioned on the substrate. A second magnetic track is positioned on the magnetic medium. Orientations of the magnetizations of the magnetic tracks are such that the substrate experiences a vertical force away from the magnetic medium.
