ABSTRACT:
A suspension for a head gimbal assembly comprises a flexure having a suspension tongue with a trailing portion. The trailing portion has a plurality of trailing pads formed thereon adapted for bonding to a trailing edge of a slider. The trailing portion is isolated from other portions of the flexure by a first slot surrounding the trailing portion. The isolated trailing portion is not affected due to the temperature change, the thermal crown change of the slider is reduced and, in turn, the variation of flying height of the slider is reduce so as to improve read/write performance of the slider. The invention also discloses a head gimbal assembly and a disk drive unit with the same.
