Abstract
There is provided a head gimbal assembly (HGA) for a disk drive. The HGA includes a slider and a flexure. The flexure includes a flexure body portion, a tongue portion with the slider affixed to the tongue portion, first and second gimbal arms extending between the flexure body portion and the tongue portion, and a dielectric layer including a first dielectric layer segment extending continuously along the first gimbal arm between the flexure body portion and the tongue portion. The flexure further includes a first patterned conductive trace electrically connected to the slider. The first patterned conductive trace is supported by the first dielectric layer segment. The first dielectric layer segment crosses and re-crosses the first patterned conductive trace along the first gimbal arm without overlying the first gimbal arm.
