Abstract
Provided is a magnetic head slider apparatus that can minimize a change in a roll angle caused by an impact force even with a submount mounted on a side surface thereof and achieve steady flying with the roll angle minimized. A dimple position and a pressure center position of a lifting force are moved in a slider width direction to thereby align a center of mass of a slider having a submount including a laser diode mounted on a side surface thereof, the dimple position, and the pressure center position of the lifting force with each other. This provides a magnetic head slider and a suspension thereof, and a magnetic disk drive apparatus offering higher recording density and higher reliability.
