Abstract
A head gimbal assembly for use with a load beam includes a gimbal, a slider for carrying a transducing head, and first and second tabs. The gimbal is configured to be supported by the load beam, and includes a gimbal tongue. At least a portion of the slider is secured to the gimbal tongue. The first tab extends from the gimbal tongue proximate a first corner of the slider. The second tab is spaced from the first tab and extends from the gimbal tongue proximate a second corner of the slider.
Claims18
A head gimbal assembly for use with a load beam, the assembly comprising:
- a gimbal configured to be supported by the load beam, wherein the gimbal includes a gimbal tongue and comprises a metallic layer;
- a slider for carrying a transducing head secured to the gimbal tongue;
- a first tab extending from the gimbal tongue proximate to but spaced laterally in from a first corner of the slider;
- a second tab spaced from the first tab and extending from the gimbal tongue proximate to but spaced laterally in from a second corner of the slider;
- and
- a polymer layer secured to the metallic layer of the gimbal, wherein the polymer layer extends along at least a portion of the first tab at a surface facing the load beam.
A head gimbal assembly comprising:
- a gimbal configured to be supported by a load beam, wherein the gimbal includes a gimbal tongue and comprises a metallic layer;
- a slider for carrying a transducing head secured to the gimbal tongue;
- a first tab extending from the gimbal tongue located near a first corner of the slider;
- a second tab extending from the gimbal tongue located near a second corner of the slider, the first tab and the second tab defining a cutout channel in the gimbal tongue extending inward from a distal end of the gimbal tongue;
- and
- a polymer layer secured to the metallic layer of the gimbal, wherein the polymer layer extends along at least a portion of the first tab at a surface facing the load beam.
