Abstract: PURPOSE:To keep the attitude angle of a head slider constant, and in addition, to facilitate the removal of an adhesive agent remaining on an arm by making the mean roughness of the center line of the bonding surface of a spacer rougher than the mean roughness of the center line of the bonding surface of the load arm. CONSTITUTION:After the spacer 1, the load arm 3 and a gimbal 2 are spot- welded, they are grinding-worked so as to remove warp caused on the spacer 1 and the arm 3. At that time, the mean roughness of the center line of the bonding surface of the spacer 1 is made rougher than the mean roughness of the center line of the bonding surface of the arm 3. Then, when a head assembly is fixed to the tip part 6 of the arm, a whole head never comes to be inclined because the spacer 1 is fixed. Further, the attitude angle of the head slider 4 at the time when the magnetic head floats on the surface of a magnetic disk 10 does not change. Besides, the adhesive agent adheres much to the surface of rough surface ruoghness, and most of it remains at the spacer 1, and the removing work of the residual adhesive agent of the surface of the tip part 6 becomes easy.
