摘要：
A head gimbal assembly includes a slider assembly and a flexure tongue that cantilevers in a first direction and supports the slider assembly. The slider assembly cantilevers away from the flexure tongue in a second direction different than the first direction. A load beam imparts a force on the flexure tongue and generates a first net torque on the slider assembly. The cantilevering of the slider assembly decreases a magnitude of the first net torque on the slider assembly. The force on the flexure tongue can also generate a second net torque on the slider assembly that is oriented about a second axis different than the first axis. The slider assembly can cantilever in the second direction to decrease the magnitude of the second net torque on the slider assembly. Portions of the flexure tongue and the slider assembly can be spaced apart from one another to form a gap that is directly between the flexure tongue and the slider assembly. The flexure tongue can includes a tongue aperture and/or one or more notches that increase the deflection of the flexure tongue to decrease the first net torque.
