Abstract
A magnetic head assembly in which a slider can be removed with deformation of a suspension suppressed and the posture angle of a magnetic head can be maintained stably and a magnetic disk drive mounted with the magnetic head assembly. A head gimbal assembly (HGA) according to an embodiment includes a suspension, a magnetic head slider provided with a magnetic head element section, and a gimbal retaining the slider and connected to the suspension. The gimbal includes a spacer formed around a conductive adhesive application area. A nonconductive adhesive application area having a planar dimension not larger than that of the conductive adhesive application area is formed outside the spacer. The gimbal and the slider are brought into conduction through a conductive adhesive applied to the conductive adhesive application area and are adhered to each other with a nonconductive adhesive applied to the nonconductive adhesive application area.
