Abstract
A head gimbal assembly includes a slider and novel gimbal that may reduce crown sensitivity to temperature without substantially sacrificing the ability of a bond between the gimbal tongue and slider to resist applied forces and torques. The gimbal has a tongue that includes at least one weakening region. The weakening region extends more in a direction perpendicular to the length of the slider than it does in a direction parallel to the length of the slider. A bonding surface of the slider is attached to the tongue in a first bonding region that extends closer to a leading end of the slider than the weakening region does, and in a second bonding region that extends closer to a trailing end of the slider than the weakening region does. The gimbal can be used in a head gimbal assembly of a magnetic hard disk drive or other information storage device.
