Abstract
A head gimbal assembly (HGA) of a hard disk drive (HDD) includes a flexure, a slider attached to the flexure and including a magnetic head, a plurality of pads at a side of the slider, a plurality of traces attached to and supported by the flexure and respectively bonded to the pads to form an electrically continuous circuit therebetween, and an insulating support element covering a bonding region between the pads and the traces.
Claims25
An HGA (head gimbal assembly) of an HDD (hard disk drive) comprising:
- a flexure;
- a slider attached to the flexure and including a magnetic head;
- at least six pads provided at a side of the slider;
- at least six traces attached to and supported by the flexure and bonded to the at least six pads to be electrically connected to the at least six pads, respectively;
- and
- an insulating support element covering bonded regions between the at least six pads and the at least six traces,
- wherein a portion of the insulating support element covering traces of the at least six traces disposed at both edges of the slider is thicker than a thinner portion of the support element covering traces of the at least six traces disposed in a center of the slider.
4 more elements
A head gimbal assembly (HGA), comprising:
- a slider to lift a magnetic head from a surface of a rotating disk through a lifting force of a pressure differential generated thereby;
- a flexure flexibly coupled to the slider to form a bonding region, the flexure being biased in a direction to oppose the lifting force;
- and
- a support element disposed in the bonding region to decrease flexibility of the flexure therein, the support element applying a force supplemental to the bias on the flexure such that the lifting force lifts the slider and the support element a predetermined distance from the rotating disk,
- wherein the support element has a predetermined cross-sectional profile of at least two distinct thicknesses.

A hard disk drive (HDD), comprising:
- a disk to rotate and generate thereby a pressure differential at the surface thereof;
- a head gimbal assembly (HGA), comprising:
- a slider to lift a magnetic head from a surface of the rotating disk through a lifting force of the pressure differential generated thereby;
- a flexure flexibly coupled to the slider to form a bonding region, the flexure being biased in a direction to oppose the lifting force;
- and
- a support element disposed in the bonding region to decrease flexibility of the flexure therein, the support element applying a force supplemental to the bias on the flexure such that the lifting force lifts the slider and the support element a predetermined distance from the rotating disk;
- and
- an actuator to position the HGA over the rotating disk,
- wherein the support element has a predetermined cross-sectional profile of at least two distinct thicknesses.
