Abstract
A HGA includes a load beam having a dimple formed thereon; a flexure including a suspension tongue and a support plate connected with the suspension tongue; and a slider having a leading edge and trailing edge opposite to the leading edge. The slider is mounted on the flexure such that the slider is supported by the dimple at the center of the slider. The leading edge is attached on the suspension tongue and trailing edge is attached on the support plate. A weight-balance structure is formed on the suspension tongue of the flexure to balance the weight of the HGA between a portion from the trailing edge to the slider center and another portion from the leading edge to the slider center. The invention also discloses various methods of manufacturing HGA with the balanced weight.
